Abstract:
1. A resin member that is mainly composed of a conductive resin material for grounding and that has a marked part formed by laser radiation, the conductive resin material comprising: a non-conductive resin material selected among a group of polyamide, polyethylene, acrylonitrile butadiene styrene, polycarbonate and polybutylene terephthalate; at least 1% by weight of metal filler as a conductive additive to give the non-conductive resin material conducting properties, wherein the conductive additive is a metal filler selected among the group of stainless steel, nickel, chromium, zinc, copper, aluminum, gold, silver, magnesium, titanium, and alloy of two or more of said metals, and combinations of two or more of said metals, wherein the conductive resin material comprises at most 30% by weight of the conductive additive; and 0.01 to 3% by weight of carbon particles to give the marked part marking properties for laser radiation, wherein the carbon particles have a mean particle diameter of 10 to 100 nm, wherein the resin member is a cap cover to open and close an inlet opening of a fuel tank of a vehicle body, the inlet opening being formed in a filler neck connected to the fuel tank, the cap cover and the filler neck form a ground path for grounding.
