Abstract

A capsule endoscope includes an image capturing unit (11) having an image capturing section that can capture images of an inside of an abdominal cavity, an illuminating unit (12) that illuminates the inside of the abdominal cavity, a power-supply unit (13) that supplies electric power to both the image capturing unit (11) and the illuminating unit 12, and a capsule casing (14) in which at least the image capturing unit (11), the illuminating unit (12), and the power-supply unit (13) are disposed. A front cover (20) of the capsule casing has an illuminating window (20a) for allowing a light L output by the illuminating unit (12) to pass through and that makes it difficult for the light L to reflect toward the image capturing unit (11).
