摘要：
A position control device 1 and a position control method of the present invention are a technology used in a shape memory alloy actuator for moving a movable member using a shape memory alloy member. In controlling the position of the movable member, an instruction value indicating a position of the movable member as a control target is changed to reduce the temperature of a shape memory alloy member when an amount of power supplied to the shape memory alloy member is in excess of a predetermined first threshold value. A drive device and an imaging device C of the present invention include a shape memory alloy actuator and the position control device 1.
