Abstract
The present invention is a resin component disposed in a path of a beam emitted from a radar equipment, the resin component consisting of a thermoplastic resin composition containing at least one thermoplastic resin selected from a group consisting of a rubbery polymer-reinforced vinyl-based resin wherein a polymer part derived from a rubbery polymer and a vinyl-based resin part containing a structural unit derived from a vinyl-based monomer are chemically bonded, a polyolefin resin, and a polycarbonate resin, and having a dielectric constant of 2.9 or less, and a mold shrinkage rate of 1.2% or less as measured in accordance with JIS K 7152-4. This resin component can be used as a radome and may constitute part of a radar device.
