<p>An imaging apparatus includes a collapsible lens barrel including plural lens groups (G1-G4) that move along a first optical axis (31) toward an opposite side of an object when the lens barrel is collapsed in a collapsing mode. The plural lens groups move along the first optical axis (31) toward the object in a photographing mode. A bending optical system includes a reflection member (RP) that reflects a light coming from the object and passing through the plural lens groups to a direction in parallel to a second optical axis substantially perpendicular to the first optical axis (32). The plural lens groups (G1-G4) and the reflection member (RP) are positioned on the first (31) and second (32) optical axes, respectively, in the photographing mode, and a prescribed space is formed by evacuating one of the plural lens groups from the first optical axis while moving the reflection member along the second optical axis in the collapsing mode. The other one of the plural lens groups is moved and installed in the prescribed space in the collapsing mode.
