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.
Claims6
An image pickup apparatus for endoscope, comprising:
- an image pickup member provided with an image pickup device and a plurality of image pickup side faces;
- a first optical member made up of a plurality of first optical elements stacked together, the first optical member being provided with a plurality of first side faces;
- a first bonding layer bonding together the image pickup member and the first optical member;
- a second optical member made up of a plurality of second optical elements stacked together, the second optical member being provided with a plurality of second side faces;
- and
- a second bonding layer bonding together the second optical member and the first optical member,
- wherein at least any of the plurality of first side faces includes a first near side face closer to an optical axis than are the second side faces and the image pickup side faces,
- at least any of the plurality of second side faces includes a second near side face closer to the optical axis than are the first side faces and the image pickup side faces,
- the first near side face is a bottom face of a first trench formed in an appropriate one of the first side faces and parallel to the optical axis,
- the second near side face is a bottom face of a second trench formed in an appropriate one of the second side faces and parallel to the optical axis,
- each of the first trench and the second trench includes a superimposed region in which the first trench and the second trench are superimposed and a non-superimposed region in which the first trench and the second trench are not superimposed when seen through in a direction of the optical axis, and
- the image pickup apparatus for endoscope further includes a sealing resin filling the first trench and the second trench and covering the first near side face, at least part of the first bonding layer, and at least part of the second bonding layer.
