A vision regeneration assist apparatus includes: a substrate including electrodes; a control unit; a mount that is formed from a sintered element made of an insulating material, the mount including through holes; an internal conductor that is to be filled into the through holes of the mount to electrically connect the control unit with wires extending from the electrodes. The internal conductor includes: a first conductive material which is to be filled to a predetermined depth from an opening of the through holes at the upper surface of the mount, the first conductive material which takes at least one type of conductive material, which is not fused at a sintering temperature of the mount; and a second conductive material which is formed from a conductive material that is to be filled into a remaining of the through holes, which faces the substrate, the second conductive material exhibiting biocompatibility.
