Abstract: A fuel tank lid includes a lid part closing an opening of a fuel tank, and an internal terminal electrically connecting a pump provided inside the fuel tank with a drive circuit driving the pump. The lid part includes an inserted part inserted into the opening, a storage part located outside the fuel tank and storing the drive circuit in a hollow space of the storage part, and a connection part located outside the fuel tank and connecting the inserted part and the storage part. The fuel tank lid further includes a discharge part discharging a fuel vapor that tries to travel along an interface between the internal terminal and the lid part and enter the hollow space, to an external atmosphere, and a protection part covering the portion exposed from the lid part by the presence of the discharge part to protect the portion from a liquid.
