To install solar battery panels in many places, to improve a corporate image and to increase a propaganda effect by providing a sign-board for displaying a symbol, etc., with a power generation function of a solar battery while keeping its appearance as it is.

This signboard is constituted so that a serially connected poly crystalline solar battery panel 13 is stuck to a transparent tempered glass plate 11 through an adhesive layer 12. Further, a symbol film 2 consisting of a transparent film 22 plotted with the symbol and the adhesive layer 23 is stuck onto the transparent tempered glass plate 11 becoming a light receiving surface of a solar battery module 1 stuck with a rear surface protection film 15 through the adhesive layer 14. The symbol is plotted so that a screen film having many elliptic small holes is laid over the transparent film 22, and after fluorescent paints of three kind colors of red, blue, green are applied onto it, the porous film is peeled, and many elliptic pixels consisting of the colored layers 21 of the fluorescent paints are formed on the transparent film 22 insularity. When this is exposed to the sunlight, the sunlight is made incident on the solar battery cell 13 to generate power.
