摘要:
In an inductor including a magnetic core on a top surface of a terminal table, a plurality of L-shaped conductors are inserted into the terminal table so that two ends of each of the L-shaped conductors are projecting from a side surface of the terminal table. The plurality of L-shaped conductors each have at least one stepped portion. One of the two ends which is on a higher level than the stepped portion acts as a winding terminal around which the wire is wound, and the other end which is on a lower level than the stepped portion acts as a mounting terminal used for mounting of the inductor. The winding terminal is projecting from a higher level of the side surface of the terminal table than the mounting terminal.
