INSPECTION DEVICE, METHOD FOR PRODUCING MULTILAYER ELECTRODE BODY AND INSPECTION METHOD

An inspection device is a device that inspects the position of an electrode plate in a multilayer body, which is obtained by bonding a separator and the electrode plate to each other by means of an adhesive, from the separator side. This inspection device is provided with: an infrared light irradiation unit that irradiates the multilayer body, from the separator side, with infrared light that has a peak wavelength within the range of from 6.5 μm to 9.6 μm; a camera that takes an image of the infrared light that transmits through the separator and is reflected by the electrode plate; and a detection unit that detects the position of the electrode plate.
