Abstract: A heater includes a heat generation element which includes a heater wire which spreads in a planar manner, and a metal plate serving as a heat dissipation element which includes a material having a high thermal conductivity, which is placed on a vehicle windowpane side of the heat generation element, which is heated by heat from the heat generation element, and which irradiates heat to the vehicle windowpane side. The vehicle windowpane is heated by the heat irradiated from the metal plate serving as the heat dissipation element.

Abstract: Provided is a sliding electric component that extends the service life of a slider, inhibits the occurrence of abnormal sounds during sliding, smooths the sliding of the slider, and inhibits the occurrence of abrasion powder from carbon paste. The sliding electric component comprises a first power collection part (12), a second power collection part (13), and a slider (15) for sliding on the first power collection part (12) and the second power collection part (13), wherein the a plurality of areas (12a, 13a) composed of carbon paste are formed in the sliding direction of the slider (15) in continuous fashion on the second power collection part (13) on which the slider (15) slides.
