PURPOSE: To provide a self-light-emitting marker of such constitution as not to put out all the light emitters even in the case of bad weather continuing long, regarding the self-light-emitting marker using a solar battery.

CONSTITUTION: An oxidation-reduction reaction battery 4 of large capacity and an electric double-layer capacitor 5 rapidly charged even with low voltage are connected to a solar battery 2. Both the electric double-layer capacitor 5 and the oxidoreduction battery 4 are therefore charged in normal fine weather where the generated power of the solar battery 2 is large, and at least the electric double-layer capacitor 5 is charged in bad weather such as rainy weather where the output voltage of the solar battery 2 is lowered. Accordingly, even in the case of the oxidoreduction battery 4 is put out of use due to electric discharge or the like in long-term bad weather so as to put out a light emitter 31 connected to this battery 4, a light emitter 32 connected to the electric double-layer capacitor 5 is kept alight.
