PROBLEM TO BE SOLVED: To secure the thermal contact of a thermoelectric element by providing a projecting part being extended to the outside of the thermoelectric element while passing among a plurality of thermoelectric elements at a watch module and fixing the module to a watch case by the projecting part. SOLUTION: A watch module 107 of a thermoelectric generation watch is provided with, for example, a plurality of projecting parts 108 that are radial outside in a radius direction and are made of plastic or the like. The projecting parts 108 are, for example, bent downward and an upper surface touches an upper drum 102 and the end of a lower surface touches a rear lid, thus fixing the module 107 in upper and lower directions. Also, a thermoelectric element module is composed by bonding ring-shaped plates 109 and 110 that are made of a metallic material with a high thermal conductivity to both the cold contacts and warm contacts of a plurality of thermoelectric elements 101 or the like using a thermally conductive adhesive or the like. Further, a thermally conductive sheet such as elastomer that is made of a filler being made of silicon rubber or the like and metal or the like is pinched adhesively, for example, between the rear lid and the ring-shaped plate 110. |
