Abstract: An inductor includes a magnetic core obtained by pressure-molding a mixture of a magnetic material powder and a binding agent, and coil elements buried in the magnetic core. The coil elements include two tabular coils that are a first coil element and a second coil element provided overlappingly in stated order from a first side face side to a second side face side. End portions of the coil elements protrude from the bottom face and are bent along the bottom face to configure external electrodes. One of first external electrodes extends toward a first end face and an other one of the first external electrodes extends toward the second end face, and second external electrodes extend toward a second side face.

Abstract: An object of the present disclosure is to achieve a small-sized inductor capable of handling a high current, and having a high coupling coefficient. Inductor includes magnetic core and coil element embedded in magnetic core. Coil element includes at least four flat coils, and first coil element, second coil element, third coil element, and fourth coil element are provided in an overlapping manner. Ends of each coil element protrude from bottom surface, and are bent along bottom surface, to form external electrode. Ends of first coil element and ends of third coil element are bent toward first side surface. Ends of second coil element and ends of fourth coil element are bent toward second side surface.

Abstract: An object is to provide a small and highly reliable inductor capable of handling a large current. The inductor includes: magnetic core formed by pressing a mixture of a powdered magnetic material and a binder; coil part disposed inside magnetic core; and external electrode formed by bending end portion of coil part protruding from magnetic core. Coil part and external electrode are made of a flat conductor, and a width of end portion of coil part protruding from magnetic core is less than an average width of coil part disposed inside magnetic core.

Abstract: Disclosed is an inductance part including a coiled conductor formed from a metal conductor, a magnetic body formed by pressure-molding a mixture of metal magnetic powder and bonding material in such a manner that the coiled conductor is embedded in the mixture, and a terminal derived from the coiled conductor. The coiled conductor is formed in a single layer with no insulating film on its surface. The metal magnetic powder of the magnetic body penetrates into the surface of the coiled conductor so as to make the filling factor of the metal magnetic powder in the magnetic body not less than 80% by volume.

Abstract: One object of the present invention is to provide a dissolved ozone decomposing apparatus which efficiently decomposes dissolved ozone in ozone water. The dissolved ozone decomposing apparatus comprises a case 2 and a first decomposing column 30 and a second decomposing column 40 in the case. The first decomposing column 30 comprises a flow pipe 31 in communication with a supply port 21, an adjustment plate 35 fixed in the flow pipe 31, a protection pipe 32 provided in the flow pipe 31 and made of a material transparent to ultraviolet rays, and a ultraviolet lamp 33 housed in the protection pipe 32, and when ozone water flows in the flow pipe 31, it strikes the adjustment plate 35 and stays in the pipe, so that the ozone water can be irradiated by light energy from the ultraviolet lamp 33 for decomposition of dissolved ozone in the ozone water.
