PROBLEM TO BE SOLVED: To inexpensively form an outer yoke and to increase the thrust of an electromagnetic linear actuator. SOLUTION: In the electromagnetic linear actuator (50) comprising a fixed part and a movable part (60) linearly moving along the axial direction to the fixed part by an electromagnetic force, the fixed part includes a magnetic circuit (70) comprising yoke members (71, 74) and a magnet (72) and the movable part (60) includes a coil (61). The yoke member is constituted of the outer yoke (71) and an inner yoke (74). The outer yoke (71) has a rectangularly cylindrical shape having a bottom formed by assembling a flat plate formed by press punching. COPYRIGHT: (C)2007,JPO&INPIT
