Abstract
An image pickup apparatus for endoscope includes: an image pickup member provided with a plurality of image pickup side faces; a first optical member provided with first side faces; a first bonding layer bonding together the image pickup member and the first optical member; a second optical member provided with second side faces; and a second bonding layer bonding together the second optical member and the first optical member, in which a plurality of first side faces include first near side faces closer to an optical axis than are the second side faces and the image pickup side faces, and the image pickup apparatus for endoscope further includes a sealing resin covering the first near side faces, at least part of the first bonding layer, and the second bonding layer.

- an image pickup member provided with an image sensor;
- a first optical member comprising one or more first optical elements stacked in an optical axis direction, the first optical member comprising:
- one or more first side faces parallel to the optical axis direction;
- and
- a first trench formed on at least one of the one or more first side faces, each first trench extending from the at least one of the one or more first side faces to a first bottom surface;
- a second optical member comprising one or more second optical elements stacked in the optical axis direction, the second optical member being at least indirectly stacked with the first optical member in the optical axis direction, the second optical member comprising:
- one or more second side faces parallel to the optical axis direction;
- and
- a second trench formed on at least one of the one or more second side faces, each second trench extending from the at least one of the one or more second side faces to a second bottom surface, wherein the first trench and the second trench including common portions overlapping in a direction orthogonal to the optical axis direction;
- and
- a sealing resin disposed in each of the first trench, the second trench and the common portions;
