1. An epoxy resin composition for a carbon fiber reinforced composite material containing an epoxy resin [B], and satisfying at least one of the following conditions (1) and (2),
wherein the epoxy resin composition is used to make a laminate with conductivity in a thickness direction by being laminated between two sheet like carbon fiber layers containing carbon fiber [A], and the conditions are as follows:
(1) thermoplastic resin particles or fibers [C] and conductive particles or fibers [D] are contained in the epoxy resin [B], wherein a weight ratio expressed by [content of [C] (parts by weight)]/[content of [D] (parts by weight)] is 1 to 1000; and(2) conductive particles or fibers having a thermoplastic resin nucleus or core coated with a conductive substance [E] are contained in the epoxy resin [B].
