1. A method for inspecting a metal separator that is formed by a first separator and a second separator welded to each other, the method comprising:
a step of positioning an imaging portion of an imaging device at a weld portion of the metal separator;
a step in which a height detector detects deflection of the metal separator in the vicinity of an imaging portion of the imaging device, and a driving device displaces the metal separator or the imaging device in a height direction according to the deflection of the metal separator, whereby a distance between the imaging device and the imaging portion of the metal separator is kept constant; and
a step of imaging the weld portion with the imaging device.
