Abstract
An infrared sensor cover includes a decorative layer, a transparent first base, and a transparent second base. The decorative layer includes a first surface and a second surface opposite the first surface. The first base is made of a resin molded body and disposed on the first surface of the decorative layer. The second base is made of a resin molded body and disposed on the second surface of the decorative layer. An absolute value of a difference between refractive indices of a first resin material of the first base and a second resin material of the second base is less than or equal to 0.05. An absolute value of a difference between heat deflection temperatures of the first resin material and the second resin material is greater than or equal to 15 degrees.
