CONDUCTIVE RESIN MEMBER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin member which has conductivity for forming an earthing passage and whose display portion is formed by the irradiation of laser. SOLUTION: A display portion DP is formed on the surface of a lid 40. The display portion DP is formed by the irradiation of laser. The lid acts as a part of an earthing passage. The lid is formed from a polyamide or the like. A metal filler and 0.01 to 3 wt. % of carbon particles are added to polyamide or the like. The conductive resin material is irradiated with laser to form a colored display portion DP. COPYRIGHT: (C)2004,JPO
