ENDOSCOPE AND METHOD FOR PRODUCING AN ENDOSCOPE

The present invention comprises: an image sensor having an imaging surface; and a lens adhered to the imaging surface by an adhesive and imaging light on the image sensor. The lens includes: a light incident surface extending in an orthogonal direction orthogonal to an optical axis direction of the lens; a rear surface parallel to the light incident surface and facing the imaging surface; a groove having an opening provided in the rear surface and an in-lens space provided between the opening and the light incident surface, the groove being recessed from the opening toward the light incident surface; an emission portion disposed in the in-lens space and emitting light from the light incident surface to the imaging surface; a frame portion disposed around the opening in the rear surface; and a protruding portion protruding from the frame portion in the optical axis direction and abutting on the imaging surface. 本发明包括：图像传感器，具有成像表面；以及透镜，通过粘合剂粘附到成像表面并且将光成像在图像传感器上。透镜包括：光入射表面，在与透镜的光轴方向正交的正交方向上延伸；后表面，与光入射表面平行并且面对成像表
