An electroconductive plate is prepared by molding an electroconductive resin composition comprising an electroconductive agent and a radical-polymerizable thermosetting resin system having an acid value in a specific range by a resin molding method. The electroconductive agent may be a carbon powder. The radical-polymerizable thermosetting resin system may comprise a radical-polymerizable resin and a radical-polymerizable diluent. The double bond equivalent of the radical-polymerizable resin is preferably about 200 to 1000. The glass transition temperature of the hardened product is preferably not lower than 120&#xb0; C. The proportion (weight ratio) of the electroconductive agent relative to the radical-polymerizable thermosetting resin system [the former/the latter] is about 55/45 to 95/5.
