Patent ID: 7198734

Claim:
An IC socket obtained by forming or molding a thermoplastic resin composition comprising: (A) 60 to 85% by mass of a thermoplastic resin, (B) 10 to 25% by mass of a carbon precursor having a volume resistivity of 10 2 to 10 10 Ω·cm, and (C) 3 to 15% by mass of an electrical conductive filler having a volume resistivity of less than 10 2 Ω·cm, wherein said thermoplastic resin (A) comprises at least one heat-resistance resin selected from the group consisting of a crystalline resin (A1) having a melting point of 220° C. or higher and an amorphous resin (A2) having a glass transition temperature of 170° C. or higher, and wherein the IC socket has a deflection temperature under load of 200° C. or higher, a surface resistivity of 10 7 to 10 11 Ω/□, and a MAX/MIN ratio of 10 or less, wherein MAX is the maximum surface resistivity thereof and MIN is the minimum surface resistivity thereof.
