The present invention has an object in providing a camera with which further miniaturization is realized, in a camera having the bending optical system. A digital camera (301) has an imaging device (2), an outer case (302), a battery (22), a memory card (24), and a sub-substrate (21). The imaging device (2) includes a lens barrel (31) having a bending optical system bending a light flux incident along a first optical axis (A1) into a direction along a second optical axis (A2) intersecting the first optical axis (A1), and a CCD unit (32) receiving a light flux taken in by the bending optical system. The outer case (302) retains the imaging device (2). At least one of the battery (22), the memory card (24), and the sub-substrate (21) is disposed so that the section thereof parallel to a plane including the first optical axis (A1) and the second optical axis (A2) is approximately rectangular, and the longitudinal direction of the section is approximately parallel to a direction along the first optical axis (A1).
