Abstract
A method for manufacturing a near-infrared sensor cover includes arranging a mask in a region of an undercoating layer formed on a rear surface of a base, the region being different from a heater formation region in which a heater is to be formed and different from a belt-shaped separation region extending along an edge of the heater formation region, forming a heat-generating film on the mask and the undercoating layer, the heat-generating film being made of the conductive heat-generating material, peeling, using a laser, the heat-generating film formed in the separation region, and removing the mask and the heat-generating film formed on the mask. The separation region has a width that is set to be smaller than a beam diameter of each of near-infrared rays transmitted from the transmitting portion.
