Electrically conductive resin composition

A resin composition comprising:

• (A) 20 to 70 parts by weight of an unsaturated polyester being radically copolymerizable, having an average molecular weight between 500 and 5000, and having a degree of unsaturation between 150 and 190,
• (B) 1 to 25 parts by weight of a thermoplastic resin having an average molecular weight between 1.times.10.sup.4 and 1.times.10.sup.7,
• (C) 30 to 70 parts by weight of a liquid of at least one ethylenically unsaturated monomer being radically reactive with said unsaturated polyester and being able to dissolve said unsaturated polyester and said thermo-plastic resin,
• (D) 0.05 to 1.0 parts by weight of an electrically conductive fiber-like material having a length between 1 and 10 millimeters and an aspect ratio between 2 and 10.sup.3, on the basis of the total amount of said unsaturated polyester, said thermoplastic resin and said ethylenically unsaturated compound being 100 parts by weight;
• and
• (E) not more than 40 parts by weight of an electrically conductive powder material having a diameter between 10 and 300 microns, on the basis of the total amount of said unsaturated polyester, said thermo-plastic resin and said ethylenically unsaturated compound being 100 parts by weight.
