Abstract
In a magnetic drive circuit of an actuator, a first yoke and a second yoke are disposed on both sides in a first direction across a coil, and a first magnet and a second magnet are fixed to the first yoke and the second yoke. The first yoke includes a first connecting plate part and a second connecting plate part that extend toward the second yoke. Thus, welding of the first connecting plate part and the second yoke and the second connecting plate part and the second yoke can be efficiently performed on a different side in the first direction (a side where the second yoke is located).
