Abstract

An in-vivo implantable medical device includes a housing, an electronic circuit component, a power reception coil, and a magnetic material. The housing is formed of a biocompatible material and forms an internal space. The electronic circuit component is disposed in the internal space. The power reception coil is disposed in the internal space, interacts with an external electromagnetic field to form an electromagnetic resonance field to receive power. At least part of a region of the housing in which the electromagnetic resonance field is formed is formed of a biocompatible nonmetal material.
