Abstract: The specific gravity of a capsule-type endoscope according to the invention is set to be lower than that of liquid in an organ, so that the capsule-type endoscope is floated on a liquid surface of the liquid. A center of gravity of the capsule-type endoscope is set to a position deviated from a center of a casing, so that the casing is maintained in a specific floating position while being floated on the liquid surface. A boundary between the casing and the liquid surface is formed within a projection plane, which is obtained by projecting the casing in the specific floating position perpendicularly to the liquid surface, at a position excluding an outer periphery of the projection plane Ka.
