Abstract: A module main body having a solar photovoltaic element is arranged on an inner surface side of a back cover, and a front cover is arranged on a front surface of the module main body. A light shielding filter is arranged in the front cover, and the light shielding filter shields light having a longer wavelength than a threshold wavelength of the solar photovoltaic element but transmits light having a shorter wavelength than the threshold wavelength toward the module main body or shields the infrared ray.

Abstract: The mouse includes a circuit board having a position detecting unit for detecting the movement of the mouse, a switch for operating the mouse, and a wireless communication unit for wirelessly transmitting the data related to the movement detected at the position detecting unit and the data related to the operation of the switch to the outside. The circuit board and a power source are mounted on a bottom part. The bottom part is covered with a housing. Electronic devices including the circuit board, the power source, and other devices are accommodated in the internal space formed by the bottom part and the housing that have resistance to and strength against the change in pressure and temperature. The entire areas of the outer surfaces of the bottom part and the housing are covered with a resin cover having elasticity, heat resistance, and waterproofness. The cover seals the internal space formed by the bottom part and the housing. The electronic devices are enclosed with a heat insulating sheet.
