First Claim
1. A lens barrel, comprising:
- a first lens configured and arranged to take in a light flux incident along a first optical axis;
a bending member including a reflecting surface configured and arranged to reflect the light flux passing through the first lens to a direction along a second optical axis intersecting with the first optical axis; and
a second lens configured and arranged to take in the light flux reflected by the bending member,at least one of the first and second lenses abutting the bending member,at least one of the bending member and the first lens including a first flat surface portion having a planar shape,the bending member and the first lens being in contact with each other via at least a part of the first flat surface portion, andthe bending member further including an entrance surface having a first region that receives the light flux exiting from the first lens, and a second region positioned on the outer peripheral side of the first region and including the first flat surface portion.

Abstract
A lens barrel includes a fourth lens, a prism, and a sixth lens. The fourth lens receives a light flux incident along a first optical axis. The prism includes a reflecting surface reflecting the light flux passing through the fourth lens to a direction along a second optical axis intersecting with the first optical axis. The sixth lens receives the light flux reflected by the prism. A second group frame includes an opening portion, a prism retaining frame that is arranged in a more inner position than the opening portion and in which the prism is contained, and a plurality of adhesive pockets arranged on an area around the prism retaining frame and being open to the side of the opening portion. Adhesive agent is filled in the adhesive pockets.
