Claim 19:
20. An image pickup apparatus for use with an endoscope, the image pickup apparatus comprising:
an image pickup member provided with an image sensor;
a first optical member comprising one or more first optical elements, the first optical member having a first outer periphery in a direction orthogonal to an optical axis direction; and
a second optical member comprising one or more second optical elements, the first optical member, the second optical member and the image pickup member being at least indirectly stacked in the optical axis direction, the second optical member having a second outer periphery in the direction orthogonal to the optical axis direction;
wherein the first outer periphery includes at least one projection projecting relative to the first outer periphery in the direction orthogonal to the optical axis direction away from an optical axis;
the second outer periphery includes at least one concavity offset relative to the second outer periphery in the direction orthogonal to the optical axis direction towards the optical axis;
no portions of the at least one projection and at least one concavity align in the optical axis direction; and
a sealing resin is disposed in the at least one cavity and around the first outer periphery other than the at least one projection.
