Endoscope

An endoscope comprising:

• an image pick-up device at a distal end part of an insertion part capable of being inserted into a body cavity,
• wherein the image pick-up device includes
• a housing member that holds an imaging lens;
• a solid-state image pick-up element that photoelectrically converts imaging light incident on an image reception surface via the imaging lens and has a rectangular shape as an outer peripheral shape of the image reception surface;
• and
• a holding member that holds the solid-state image pick-up element in a state where the image reception surface intersects a longitudinal direction of the insertion part,
• wherein the holding member has a fitting part fitted to the housing member, and an extending wall part that extends in the longitudinal direction from the fitting part to cover at least a portion of the outer peripheral surface of the solid-state image pick-up element, and
• wherein the fitting part and the extending wall part are integrally configured.
