PROBLEM TO BE SOLVED: To improve the responsiveness of an actuator using an SMA (Shape Memory Alloy) wire in a cooldown time. SOLUTION: This imaging apparatus is configured to fall in a state wherein (the spring force of a second pushing spring 21)<(the spring force of a first pushing spring 16) in a state of Figure 4(a), (the spring force of the second pushing spring 21)≤(the spring force of the first pushing spring 16) in a state of Figure 4(b), and (the spring force of the second pushing spring 21)<(the spring force of the first pushing spring 16) in a state of Figure 4(c).
