The present invention is a resin component disposed in a route of a beam emitted by a radar device, the resin component comprising a thermoplastic resin composition containing at least one type of thermoplastic resin selected from a polyolefin resin, a polycarbonate resin, and a rubbery-polymer-reinforced vinyl resin in which a polymer part derived from a rubbery polymer and a vinyl resin part derived from a vinyl monomer are chemically bonded, the relative permittivity of the resin component being 2.9 or lower, and the molding shrinkage thereof measured in accordance with JIS K 7152-4 being 1.2% or less. This resin component can be used as a radome and can constitute part of a radar device. |
