This capsule endoscope has: an image pickup element substrate unit having an image pickup element mounted thereon a signal processing substrate unit, which controls photographing of a subject, and which has a signal processing unit mounted thereon a lighting substrate unit having a plurality of light emitting elements mounted thereon a first wiring substrate unit having wiring of signals formed thereon, said signals passing between the lighting substrate unit and the image pickup element substrate unit and a second wiring substrate unit having wiring of signals formed thereon, said signals passing between the image pickup element substrate unit and the signal processing substrate unit. The capsule endoscope houses a flexible substrate wherein the lighting substrate unit, first wiring substrate unit, image pickup element substrate unit, second wiring substrate unit, and signal processing substrate unit are integrally formed in a shape wherein the substrate units are aligned in this order in a row. The capsule endoscope is provided with a lighting control circuit that has: a lighting control signal output unit that outputs lighting control signals for controlling light emission of the light emitting elements that are provided in a lighting unit and a lighting drive unit that drives each of the light emitting elements corresponding to the lighting control signals inputted from the lighting control signal output unit. The lighting drive unit is disposed on the image pickup element substrate unit or the lighting substrate unit.Linvention concerne un endoscope à capsule qui comprend : une unité de substrat délément de capture dimage ayant un élément de capture dimage monté sur cette dernière une unité de substrat de traitement de signal, qui commande la photographie dun sujet, et qui a une unité de traitement de signal montée sur cette dernière une unité de substrat déclairage ayant une pluralité déléments électroluminescents montés sur cette dernière une première unit
