1. An in-vivo implantable electronic device, comprising:
a housing including a biocompatible material and configured to define an internal space sealed;
a coil disposed in the internal space and configured to interact with an electromagnetic field generated by an external electric field or magnetic field and receive power, or an antenna disposed in the internal space and configured to transmit an electric signal to an outside or receive an electric signal from an outside by using a radio wave; and
an electronic circuit disposed in the internal space, connected to the coil or the antenna, and configured to perform at least processing of an electric signal,
wherein the housing is configured to include
a first member in a box shape made of a biocompatible metal material and having an opening,
a second member made of a biocompatible nonmetal material and having a shape that closes the opening, and
a flexible packing in an annular shape disposed between the first member and the second member, wherein the flexible packing is disposed directly between the first member and the second member, wherein the second member comprises an upper surface, a lower surface, and an outer peripheral edge disposed between the upper surface and lower surface, and the flexible packing is in direct contact with the lower surface and the outer peripheral edge of the second member when viewed in cross section.
