Poor contact on a terminal face that is likely to especially occur with a dry battery with low electromotive force can be appropriately inspected and suppressed. Moreover, the inspection can be highly efficiently performed in a non-contacting state. Also, a cylindrical dry battery in which the poor contact on the terminal face is certainly suppressed is provided. An apparatus 50 that inspects an electric contact at an outer surface of a positive terminal 12 and a negative terminal 32 of a dry battery 10, includes: a light-emitting section 51 that makes a light incident on a part to be measured on a terminal face of the battery; a light-receiving section 52 that detects a reflection state of the light from the part to be measured, and a measurement processing section 55 that quantifies gloss level of the part to be measured based on detection with the light-receiving section 52, wherein evaluation data of the electric contact is obtained with measurement values of the gloss level.
