Original Abstract Submitted
a housing of an in-vivo implantable medical device includes a window including a nonmetallic biocompatible material that enables formation of an electromagnetic resonance field and radio communication. in plan view of the housing, an outer shape of the window is larger than an outer shape of a power receiving coil. an outer shape of a magnetic sheet is larger than the outer shape of the power receiving coil to form a magnetic circuit that serves as a main magnetic flux that forms an electromagnetic resonance field to obtain power for the power receiving coil. a radio communication antenna is at a position where the main magnetic flux does not intersect. an outer shape of the radio communication antenna has an area of 1/100 or less of the outer shape of the power receiving coil.
