20080281160CAPSULE-TYPE MEDICAL APPARATUS AND METHOD OF MANUFACTURING CAPSULE-TYPE MEDICAL APPARATUS - The present invention provides a capsule-type medical apparatus and a method of manufacturing a capsule-type medical apparatus which can prevent a contact between a burr formed on an optical dome which is a part of a capsule-like casing and a living body in a subject. The capsule-type medical apparatus has a capsule-like casing which can be introduced inside the subject. The casing is configured with optically transparent optical domes and a cylindrical trunk member having an outer diameter dimension larger than an outer diameter dimension of the optical domes.
