REFLECTION MIRROR FOR CAR

摘要

PURPOSE:To utilize effectively heat emitted from a metallic film by forming a heat ray reflecting layer for reflecting the heat toward the surface of a reflection mirror for a car. CONSTITUTION:A metallic film 2 of an Ni-Cr alloy is vacuum deposited on the front side of a glass substrate 1 as a reflecting layer which doubles as a heating element, and a transparent thin dielectric film 3 of titanium oxide is vacuum deposited on the film 2. Each electrode 4 as a means of supplying electric current to the film 2 is made of an electrically conductive resin material or the like having lower resistivity than the film 2. One end of the electrode 4 is interposed between the films 2, 3, the electrode 4 is extended along the side of the substrate 1, and the other end is positioned at the rear side of the substrate 1. A lead wire 5 is connected to the other end positioned at the rear side of the substrate 1.
