PROBLEM TO BE SOLVED: To provide an electronic scope for endoscopes facilitating wiring of conductor wires to be connected to an image pick-up device, and an assembling method of the electronic scope for endoscopes.SOLUTION: The electronic scope for endoscopes includes: an image pick-up device for capturing an image of a subject to generate an imaging signal an insertion tube to be inserted into a body cavity a conductor insertion path formed in the insertion tube a relay board having a connector and being long in a prescribed direction a plurality of conductor wires having one ends connected to the relay board and the other ends connected to the image pick-up device respectively, pulled out from the relay board in a direction substantially in parallel to the prescribed direction and laid out in the conductor insertion path across the full length thereof and a circuit board having a receptacle removably connected to the connector. The relay board has such a size as to be insertable into the conductor insertion path, with the prescribed direction matching an axial direction of the conductor insertion path.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】撮像素子に接続される導線の配線が容易な内視鏡用電子スコープ及び内視鏡用電子スコープの組立方法を提供する。【解決手段】内視鏡用電子スコープを、被写体を撮像して撮像信号を生成する撮像素子と、体腔内に挿入される挿入管と、挿入管内に形成された導線挿入路と、コネクタを有し、所定の方向に長尺な中継基板と、一端が中継基板に、他端が撮像素子にそれぞれ接続され、中継基板から所定の方向と略平行な方向に引き出され且つ導線挿入路内をその全長に亘って引き回されている複数の導線と、コネクタと着脱可能に接続されるレセプタクルを有する回路基板とから構成する。中継基板は、所定の方向を導線挿入路の軸線方向に合わせた状態で導線挿入路に挿通可能なサイズを有する。【選択図】図4
