摘要： 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.

摘要： An insulation inspection device includes: a conveyance unit that conveys a laminated electrode in which a first separator, a first electrode plate, a second separator, and a second electrode plate are laminated; a pressure roll that presses the laminated electrode against the conveyance unit; a first terminal electrically connected to the first electrode plate; a second terminal electrically connected to the second electrode plate, further electrically connected to the conveyance unit when the first separator is disposed on the conveyance unit side, and further electrically connected to the pressure roll when the first separator is disposed on the pressure roll side; and an insulation inspection unit that applies a voltage to the laminated electrode to inspect insulation condition of the laminated electrode.
