PURPOSE:To improve the resolution of an endoscope, to prolong its life, and to output image information as a television signal by sealing a solid-state image pickup element which constitutes an image pickup means airtightly with a metallic cap which has a transparent window and forming this metallic cap and a metallic frame in one body. CONSTITUTION:The metallic cap 9 with the glass window which covers the state image pickup element 8 mounted on a chip carrier 7 airtightly is arranged. Further, the metallic frame 10 is formed integrally 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 chip, plural decoupling capacitors, etc., forming 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 resin 13. Consequently, the resolution is high, the life is prolonged, and the image information is led out as the television signal.
