Abstract
An inspection apparatus comprises a fixed unit including a control device and a measurement device, and a moving unit including contact terminals, which are brought into contact with contacts formed on a printed board having electrode patterns subjected to electrical inspection (e.g., electrical conduction inspection). The contact terminals are connected to a connection switching device via a plurality of first wires, wherein the connection switching device is arranged in the moving unit for selectively switching over the first wires. A plurality of third wires are arranged for establishing connections between the fixed unit and the selectively-switched first wires, wherein the number of the third wires is smaller than that of the first wires.
