An object of the present invention is to provide an image pickup apparatus for an endoscope which has a structure capable of reliably securing the connection fixing state between the image pickup substrate and the relay board by preventing the flying lead section from coming off the relay board, A first circuit board 51 provided with a lead portion 51a made of a conduction layer between two or more insulating layers, and a second circuit board 51 provided on the first circuit board, in which the insulating layer is hollowed out and a part of the lead portion is exposed Window portions 51b and 51c and second circuit board 50 to which circuit pattern 50a is formed and soldered to the lead portion where the circuit pattern is exposed to the window portion in a state overlapped with the first circuit board Become.本発明は、フライングリード部の中継基板からの抜けを抑止し撮像基板と中継基板との接続固定状態を確実に確保し得る構造を有する内視鏡用撮像装置を提供することを目的とし、そのために2以上の絶縁層の間に導通層からなるリード部51aが配設された第1の回路基板51と、第1の回路基板に設けられ絶縁層がくり抜かれリード部の一部が露出する窓部51b,51cと、回路パターン50aが形成され第1の回路基板と重ねられた状態で回路パターンが窓部に露出されたリード部と半田固定される第2の回路基板50とを備えてなる。
