Patent ID: 8721524

Claim:
An endoscope comprising: an elongated insertion portion inserted in an examination object; an electrical component which is provided in a distal end portion on a distal end side in an insertion direction of the insertion portion and is driven by supply of electric power; a rectangular-shaped image pickup portion which is provided in an inside of the distal end portion covered by a tubular cover member configuring an outer circumference of the distal end portion, so as to be located on a rear end side in the insertion direction than the electrical component, and which picks up an image of the examination object; a power supply line for power supply, a distal end in the insertion direction of which is positioned on the rear end side in the insertion direction than the image pickup portion in the inside of the distal end portion covered by the cover member, the power supply line being inserted in the insertion portion; and a thin plate-like flexible substrate which extends along the insertion direction in a space, the space being circumscribed by an outer circumferential surface of the image pickup portion in the distal end portion and an inner circumferential surface of the distal end portion, the thin plate-like flexible substrate electrically connecting a contact of the electrical component to the distal end of the power supply line, wherein the flexible substrate is supported on one side thereof by a fixing member formed of an insulating material and on an opposed side thereof by a filler material.
