PURPOSE:To improve the resolution of an endoscope, to prolong its life, and to lead out image information as a television signal by sealing a solid-state image pickup element which constitute an image pickup means airtightly with a metallic cap having a transparent window. CONSTITUTION:The solid-state image pickup element 8 is mounted on a chip carrier 7 and the metallic cap 9 with the glass window is arranged which seals the solid-state image pickup element 8 air-tightly. Further, a metallic frame 10 is arranged along the outer periphery of the metallic cap 9 with the glass window. This image pickup means 6 is fixed on a flexible wiring board 12 where circuit elements 11 such as a transistor, plural resistance chips, and plural decoupling capacitors which form an emitter follower circuit for the impedance conversion of the image pickup signal from the solid-state image pickup element 8 are mounted. Then the joint part between the chip carrier 7 and flexible wiring board 12 is sealed with organic insulating resin 13. Consequently, the resolution is high, the life is long, and the image information can be led out as the television signal.
