CAPSULE MEDICAL DEVICE AND METHOD OF PRODUCING CAPSULE MEDICAL DEVICE

摘要

A capsule medical device in which a variation in a relative positional relationship between an optical dome, a lighting section, and an optical unit of a capsule housing is suppressed to allow highly accurate determination of the optimum positions of the lighting section and of the optical unit relative to the optical dome. The capsule medical device has optical domes (2b, 2c), lighting substrates (19a, 19f) on which respective light emitting elements (3a-3d, 6a-6d) for lighting the inside of a subject through the optical domes (2b, 2c) are mounted, optical units (4, 7) for forming images of the inside of the subject on solid-state imaging elements (5, 8), and positioning sections (14, 15) on which the respective lighting substrates (19a, 19f) and the respective optical units (4, 7) are arranged and fixed. The positioning sections (14, 15) are each fitted and fixed to the inner peripheral surface of the optical dome (2b, 2c) and each determine the positions of the light emitting element (3a-3d, 6a-6d) and of the optical unit (4, 7) relative to the optical dome (2b, 2c).
