Conventionally, a charging device connected to a commercial power source has been used to charge the mobile terminal device. When the mobile terminal device is charged by the charging device, the mobile terminal device is fixed to the charging device, and the charging device is charged while being connected to a commercial power source or the like installed indoors. Therefore, while the mobile terminal device is being charged, the mobile terminal device cannot be freely carried outdoors, and the charging of the mobile terminal device is limited to indoors.
On the contrary, when the portable terminal device is carried outdoors, the portable terminal device cannot be charged.

Therefore, in recent years, a charging device provided with a solar cell panel for receiving sunlight to generate power has been proposed, which allows the portable terminal device to be charged even outdoors without a power source. For example, when the mobile terminal device is carried outdoors, the charging device to which the mobile terminal device is fixed is attached to the outside of the bag or clothes, and the solar cell panel receives sunlight, whereby the mobile terminal device is charged. Will be.
