Abstract
A small-size inductor for use in a wrist watch or a pocket size calculator includes a base member, a coil and a cap member. The base member is defined by a base plate having first and second opposite faces, a core projection extending from the first face of the base plate, and first and second terminals deposited in a spaced relation with each other on the second face of the base plate. The base plate has at least first and second recesses formed in its peripheral face. The coil is mounted on the core projection. The coil has first and second lead wires, in which the first lead wire extends through the first recess and is connected to the first terminal and the second lead wire extends through the second recess and is connected to the second terminal. The cap member is fittingly mounted on the base member to enclose the coil in a cavity defined by the cap member and the base member.
