PROBLEM TO BE SOLVED: To provide a solar panel capable of improving output current by dispersing decrease in a light-receiving area due to a pointer by a plurality of solar cells, and a timepiece.SOLUTION: A solar panel 3, above which a pointer 7 attached to a pointer shaft 6 inserted in a through-hole 3a of a center part moves, has a plurality of solar cells 11-16 arranged nearly circularly. The plurality of solar cells 11-16 are formed of divided pieces each having a nearly spiral shape, where the pointer 7 overlaps two of the plurality of solar cells 11-16. Therefore, because the pointer 7 can be always superimposed on and astride two of the plurality of solar cells 11-16, decrease in a light-receiving area due to a pointer 7 can be dispersed by the two of the plurality of solar cells 11-16, and decrease in output current of the plurality of solar cells 11-16 on which the pointer 7 is overlapped can be suppressed, thus improving the output current of the whole solar cells 11-16. |
