PROBLEM TO BE SOLVED: To increase a force of an ampere which operates a coil efficiently. SOLUTION: An electro-mechanical converter includes a movable coil type linear motor 4a having yokes 2 provided on surfaces of N-pole and S-pole of a permanent magnet 1 and becoming a C-shaped sectional shape as a whole. End faces 2s, 2n of opposite side of the permanent magnet 1 of the end faces of the yoke 2 are disposed in parallel to form a gap. A movable part 3 is provided in the gap, and can move in parallel to the end faces 2s, 2n. The movable part 3 has a ferromagnetic conductor 5f. COPYRIGHT: (C)2005,JPO&NCIPI
