Abstract
A fuel pump has a pump function of sucking fuel in a fuel tank and discharging fuel, and a detection function of detecting a capacitance correlated to a concentration of alcohol in fuel in the fuel tank. The fuel pump includes a pump main body that is received in the fuel tank to perform the pump function, a housing electrode that covers the pump main body in the fuel tank, and an outside electrode that is located outside of the housing electrode in the fuel tank. A gap is formed between the outside electrode and the housing electrode to give the capacitance.
