To provide an inspection method of a fuel cell for shortening an inspection time.

The inspection method of the fuel cell includes: a first step of applying DC voltage at a first voltage value to a power generation body which includes an electrolyte membrane, an anode side catalyst layer arranged on one side of the electrolyte membrane, and a cathode side catalyst layer arranged on the other side of the electrolyte membrane layer, in a first term; and a second step of detecting a value of current flowing in the power generation body while applying DC voltage at a seconde voltage value which is lower than the first voltage value to the power generation body in a second term after the first term.
