PROBLEM TO BE SOLVED: To provide a novel technique for adjusting a curvature amount of an image surface of an imaging element.SOLUTION: The imaging device includes: an imaging element having a first surface including an imaging area and a second surface on the opposite side of the first surface; and an expansion/contraction member coupled to the second surface of the imaging element. The expansion/contraction member can be expanded or contracted along the second surface in response to an electric signal input to the expansion/contraction member. As the expansion/contraction member expands along the second surface, a curvature amount of the first surface becomes large.SELECTED DRAWING: Figure 1 |
