PROBLEM TO BE SOLVED: To provide a watch in which the power generation efficiency of a thermal power generation unit is good. SOLUTION: In a watch, an electricity storage member which can be charged is provided, an upper drum 220 which is made of a heat conductive material is provided, and a rear lid 226 which is made of a heat conductive material is provided. In a thermal power generation unit 180, one or more thermoelectric elements 140 are housed, a first heat conducting plate 120 which constitutes a heat absorbing plate is contained, and a second heat conducting plate 170 which constitutes a heat sink and which is constituted so as to be capable of transmitting heat to the upper drum 220 is contained, A heat conducting spacer 320 is made of a heat conductive material, and it is arranged so as to come into contact with the first heat conducting plate 120 and with the inside face of the rear lid 226. A lower drum 224 which constitutes a heat insulating member heat-insulates the rear lid 226 from the upper drum 220. |
