  • Patent number: 11875927
    Abstract: A coil component includes a core including a winding core portion and a first flange portion that is disposed on a first end portion of the winding core portion in a direction in which the winding core portion extends. A first curved portion is formed at a connection between a bottom surface of the winding core portion and the first flange portion. A ratio of a length of the first curved portion in a height direction to a distance in the height direction between the bottom surface and a first terminal electrode is no less than 20% and no more than 60% (i.e., from 20% to 60%).

  • Publication number: 20220165487
    Abstract: A coil component includes a core, terminal electrodes, and a wire. The core includes a winding core and a pair of flanges. Each flange of the pair of flanges is disposed on the corresponding one of two ends of the winding core. The terminal electrodes are at the flanges. The wire is wound around the winding core. Two ends of the wire are electrically connected to the respective terminal electrodes. The terminal electrodes each include an electrode main body part and an anchor part that extends from the electrode main body part and is lodged in the core.

  • Publication number: 20180085853
    Abstract: A treatment apparatus includes a feeding device and a laser device. The feeding device includes a feeding rotor and a motor. The feeding rotor is rotatably supported. In the outer peripheral surface of the feeding rotor, a support portion extending in a circumferential direction of the feeding rotor is formed, and holding grooves are formed in the support portion at equal angular intervals. The laser device treats the element body fed to a treatment position. A control device controls the motor so as to stop the feeding rotor at every predetermined angle (an angle at which the holding groove is formed) and to feed the element body to a treatment position. Then, the control device controls the laser device so as to treat a surface of the element body.
