An inspecting apparatus inspects a tampon that includes a tampon main body that has a cord and an applicator that is cylindrical and that accommodates the tampon main body in such a manner that the cord is exposed from a rear end of the applicator. The inspecting apparatus includes a suction mechanism that extends the cord along a longitudinal direction of the tampon by sucking air, and a cord-length inspecting mechanism that inspects a length of the cord while the suction mechanism is sucking the air.
