Patent ID: 8084191

Claim:
A manufacturing method for a thermoelectric module in which: a pair of insulating substrates are arranged in opposition; electrodes are formed at prescribed locations on the opposing inside surfaces of said insulating substrates; and the end faces of a plurality of thermoelectric elements are soldered to the respective opposing electrodes, to fix in place said thermoelectric elements between said pair of insulating substrates, said manufacturing method comprising: a resist layer formation step of forming a resist layer on one surface of said insulating substrate; an exposure step of exposing the surface of said resist layer, in a state of masking prescribed portions of the surface of said resist layer formed in said resist layer formation step; a development step of removing the masked portions in said resist layer through development of the resist layer exposed in said exposure step to form a resist pattern; an electrode formation step of forming electrodes, consisting of a plurality of metal layers, on said one surface of said insulating substrate other than portions where said resist pattern is formed in said development step; a resist layer removal step of removing said resist layer of prescribed shape; and, an visor formation step of removing a portion of the side portion of a metal layer on said insulating substrate side, among the plurality of metal layers of said electrodes, to form a visor portion on the edge portion of said electrodes.
