Patent ID: 8547478

Claim:
A lens barrel, comprising: a first lens configured to receive a light flux incident along a first optical axis; a bending member including a reflecting surface configured to reflect the light flux passing through the first lens to a direction along a second optical axis intersecting with the first optical axis; a second lens configured to receive the light flux passing through the bending member; and a lens frame to which the bending member is fixed, the lens frame including a plurality of concave portions being open to an opposite side to the reflecting surface in a direction along the first optical axis, a supporting surface being in contact with the first lens along the first optical axis, and a non-contact surface formed on an area around the concave portions and arranged closer to the reflecting surface in a direction along the first optical axis than the supporting surface, the supporting surface being perpendicular to the first optical axis, and ultraviolet cure adhesive agent being filled in the concave portions to fix the bending member to the lens frame.
