An imaging apparatus includes a bending optical element, a front lens group and a rear lens group. The front lens group and the rear lens group are provided on a pre-bending optical axis and a post-bending optical axis of the bending optical element, respectively. The front lens group includes a cut surface formed as an inclined flat surface on an outer edge of the front lens group on a side near the rear lens group, the inclined flat surface lying on a plane orthogonal to a first reference plane, which includes the pre-bending and post-bending optical axes. The inclined flat surface is inclined to a second reference plane, which is orthogonal to the first reference plane and includes the post-bending optical axis, to approach the second reference plane in a direction from an incident surface of the front lens group to an exit surface thereof. |

1. An imaging apparatus comprising a bending optical element, a front lens group and a rear lens group,
wherein said front lens group and said rear lens group are provided on a pre-bending optical axis and a post-bending optical axis of said bending optical element, respectively, wherein said front lens group includes a cut surface which is formed as an inclined flat surface on a portion of an outer edge of said front lens group on a side near said rear lens group, said inclined flat surface lying on a plane that is orthogonal to a first reference plane, which includes said pre-bending optical axis and said post-bending optical axis, and wherein said inclined flat surface is inclined to a second reference plane, which is orthogonal to said first reference plane and includes said pre-bending optical axis, to approach said second reference plane in a direction from an incident surface of said front lens group to an exit surface thereof. |
