POWER GENERATOR WITH SOLAR BATTERY AND WATCH WITH SOLAR BATTERY

To improve power generating efficiency of a solar battery 30, and suppress reduction of aesthetic property.SOLUTION: A wrist watch 1 has: a dial plate 10 including a light color part W and a dark color part BK having higher light transmissivity than light color part W, which a user can view; and a solar battery 30 which generates power by making light transmitted through the dial plate 10 be incident into the battery. In the solar battery 30, a power generation amount of power generation by incidence of a blue light component B and a green light component G is larger than power generation by incidence of red light component R out of visible light, and the dial plate 10 includes an absorption layer 11 which absorbs the red light component R at higher light absorption rate than light absorption rate to the blue light component B and the green light component G in the dark color part BK.SELECTED DRAWING: Figure 2 【課題】太陽電池３０の発電効率の向上を図ると共に、審美性が低下することを抑制する。【解決手段】腕時計１は、淡色部Ｗと、淡色部Ｗより光透過率の高い濃色部ＢＫとを含む、ユーザが視認可能な文字板１０と、文字板１０を透過した光が入射することにより発電する太陽電池３０と、を有し、太陽電池３０は、可視光のうち赤色の光成分Ｒの入射による発電よりも、青色の光成分Ｂ及び緑色の光成分Ｇの入射による発電の発電量が大きく、文字板１０は、濃色部ＢＫにおいて、青色の光成分Ｂ及び緑色の光成分Ｇに対する光吸収率よりも高い光吸収率で赤色の光成分Ｒを吸収する吸収層１１を含む。【選択図】図２
