To provide an endoscope suppressed in increase in diameter of the tip end thereof even with a long transmission cable for video signals obtained from an imaging part disposed on the tip end part, and also stabilize the operation of the imaging part to obtain high-resolution video signals.SOLUTION: An endoscope includes: a scope where a hard part is provided on the tip end of a flexible and long soft part; an imaging part housed in the hard part and having an image sensor; a transmission cable which is inserted into the scope and has a tip end conductively connected to the image sensor vie a substrate; and a voltage conversion element which is mounted on the substrate and outputs constant voltage to the image sensor with respect to voltage input into the transmission cable.SELECTED DRAWING: Figure 4 【課題】先端部に配置された撮像部から得られる映像信号の伝送ケーブルが長尺であっても先端部の大径化を抑制するとともに、撮像部を安定動作させて高解像度の映像信号を得る。【解決手段】内視鏡は、可撓性を有する長尺の軟性部の先端に硬性部が設けられたスコープと、硬性部に収容されてイメージセンサを有する撮像部と、スコープに挿通されイメージセンサに先端が基板を介して導通接続される伝送ケーブルと、基板に実装されて伝送ケーブルに入力された電圧に対して一定の電圧をイメージセンサへ出力する電圧変換素子と、を備える。【選択図】図４
