<p>A capsule type endoscope (1) having a capsule section (2) consisting of a body (3) and a viewing-side cover (4). A viewing optical section (6), an illuminating section (7), a plurality of peripheral circuit components (8a, 8b, 8c) and a power supply section (9) are disposed in the capsule section (2). The illuminating section (7) comprises an illumination board (21) disposed on the outer circumferential side of a lens frame (14), an EL element (22) formed of a thin or thick film, and various electronic components (23, 24) forming an emission control circuit. The EL element (22) is formed or arranged on the entire surface of the illumination board (21). An object is illuminated uniformly with illumination light having uniform luminance through surface emission of the EL element (22). Consequently, the optical image of the object imaged by means of an imaging element (13) is displayed as a good endoscopic image on the screen of a display.</p> |
