Abstract: An inexpensive shielded-type inductor is disclosed to include a first powder compact member, a coil embedded in the first powder compact member with the bottom side of the coil body thereof kept in flush with the bottom side of the first powder compact member and two metal terminals thereof extending from the two opposite ends of the coil body to the outside of the first powder compact member, and a second powder compact member bonded to the bottom side of the first powder compact member to determine the inductance value of the inductor subject to the thickness of the second powder compact member and to protect the inductor against external environmental factors.

Abstract: A porous ceramic member preparation method includes the step of mixing powdered silicon carbide and a resin at a predetermined ratio with a solvent to form a paste for enabling the resin to be covered on the surface of the powdered silicon carbide and the solvent to be fully vaporized, the step of processing the paste into a predetermined shape, the step of heating the shaped material at a low heating temperature to cure the resin, and the step of sintering the shaped material into a ceramic member having pores therein.
