PROBLEM TO BE SOLVED: To provide an arrangement of lighting control circuits and a wiring between the circuits best suited for a capsule endoscope.SOLUTION: The capsule endoscope comprises a flexible substrate on which the following substrate units are arranged in a row and integrally molded in the order of description: a lighting substrate unit having a plurality of light emitting elements mounted on a lighting part for projecting light to a subject a first wiring substrate unit forming the wiring for signals transmitted between the lighting substrate unit and an image pickup element substrate unit the image pickup element substrate unit having an image pickup element mounted thereon and a signal processing substrate unit having a signal processing unit mounted thereon. The capsule endoscope further comprises a lighting control circuit having: a lighting control signal output unit which outputs lighting control signals for controlling light emission of the light emitting elements mounted on the lighting part and a lighting drive unit which drives each of the light emitting elements in response to the lighting control signals inputted from the lighting control signal output unit. The lighting drive unit is disposed on one of the image pickup element substrate unit and the lighting substrate unit.COPYRIGHT: (C)2016,JPO&INPIT【課題】カプセル内視鏡に最適な照明制御用の回路の配置と回路間の配線とを提供する。【解決手段】被写体に対して光を照射する照明部に備えた複数の発光素子が実装される照明基板部、照明基板部と撮像素子基板部との間を通る信号の配線が形成される第1の配線基板部、撮像素子が実装される撮像素子基板部、照明基板部と撮像素子基板部との間を通る信号の配線が形成される第1の配線基板部、信号処理部が実装される信号処理基板部の順番で、それぞれの基板部が一列に並んだ形状に一体成形されたフレキシブル基板が収納されるカプセル内視鏡において、照明部に備えた複数の発光素子の発光を制御するための照明制御信号を出力する照明制御信号出力部と、照明制御信号出力部から入力された照明制御信号に応じて発光素子のそれぞれを駆動する照明駆動部とを有する照明制御回路を備え、照明駆動部は、撮像素子基板部および照明基板部のいずれか一方に配置される。【選択図】図2
