Abstract: An analysis device includes an analysis unit configured to receive scattered light, transmitted light, fluorescence, or electromagnetic waves from an observed object located in a light irradiation region light-irradiated from a light source and analyze the observed object on the basis of a signal extracted on the basis of a time axis of an electrical signal output from a light-receiving unit configured to convert the received light or electromagnetic waves into the electrical signal.

Abstract: Provided is a glass panel having a glass plate with a solar battery element, which is capable of protecting a light-modulating sheet from the heat of sunlight to control a temperature increase in the light-modulating sheet. A glass panel characterized in that a solar battery element and a light-modulating element are disposed between a first glass plate on a sunlight incident side and a second glass plate on a sunlight exit side sequentially from a first plate glass side, and a heat reflective element is interposed between the solar battery element and the light-modulating element.
