Decorative component for vehicle

A decorative component for a vehicle includes a decorative body portion having millimeter wave transmittance and a heating sheet. The decorative body portion is configured to decorate the vehicle by being attached to part of a vehicle on a leading side in a transmitting direction of millimeter waves from a millimeter wave radar device. The heating sheet includes a plastic sheet and a wire-shaped heater provided on the plastic sheet. At least a main portion of the heating sheet is provided integrally with the decorative body portion.

A steering wheel including a rim, first heating members, second heating members, and a control section is provided. The rim has leather-covered portions and wood-grain portions. The surface of the leather-covered portions has a thermal conductivity different from the thermal conductivity of the surface of the wood-grain portions. Each first heating member is provided inside of the surface of the corresponding leather-covered portion. When being energized, each first heating member adjusts the surface temperature of the corresponding leather-covered portion. Each second heating member is provided inside of the surface of the corresponding wood-grain portion. When being energized, each second heating member adjusts the surface temperature of the corresponding wood-grain portion. The control section controls the energization of the first heating members and the energization of the second heating members independently from each other.
