A vision regeneration assisting apparatus for regenerating vision by applying electrical stimulation to cells that compose a retina, the apparatus comprising: a substrate formed in a thin plate shape of insulating and bendable material, provided with a plurality of first lead wires being wired therein and an electrode for outputting an electrical stimulation pulse signal being provided at one end of each of the first lead wires; a multiplexer for distributing the electrical stimulation pulse signal to each electrode; a base formed of sealing and insulating material, one face of which being united to the substrates and the other face of which being united with the multiplexer, and provided with a plurality of second lead wires for connecting the multiplexer and each of the first lead wires in the substrate being wired therein; and a cap formed of sealing material, and united to the base so that the multiplexer is to be hermetically sealed. In this manner, a circuit of an internal device installed at the patient's intra-body (intra-eye) can be easily and reliably hermetically sealing.
