Abstract
A fiber-reinforced composite material including reinforcing fiber layers and a resin layer sandwiched therebetween, wherein conductive particles having a sphericity of 85% or more are disposed in the resin layer, and the fiber-reinforced composite material has a portion where upper and lower reinforcing fiber layers are connected by one conductive particle and has a portion where a conductive particle is sunk in a reinforcing fiber layer. Provided is a fiber-reinforced composite material having sufficient electrical conductivity in a thickness direction with a small addition amount of conductive particles.

A fiber-reinforced composite material comprising reinforcing fiber layers and a resin layer sandwiched therebetween,
- wherein conductive particles having a sphericity of 85% or more are disposed in the resin layer, and the fiber-reinforced composite material has a portion where upper and lower reinforcing fiber layers are connected by at least one conductive particle and has a portion where the at least one conductive particle is sunk in a reinforcing fiber layer, which means that a boundary line of the reinforcing fiber layer in contact with the conductive particle is recessed in an arc shape that is along the shape of the conductive particle with a recess depth of 15 μm or more.
