PROBLEM TO BE SOLVED: To provide an electroconductive composite material in which a metallic mesh and a fiber preform are integrated without causing decrease in strength, even if the electroconductive composite material is large in area.SOLUTION: An electroconductive composite material 11 is the electroconductive composite material combined with a matrix resin while a planar fiber preform 12 and a planer metal mesh 13 are accumulated. The surface of the matrix resin which covers the surface of the fiber preform 12 is formed in arithmetic average roughness Ra to 0.1-1.0 μm, and the surface of the matrix resin with which the surface of metal mesh 13 is covered is formed in the arithmetic average roughness Ra to 10 μm or more as a whole and a numerical aperture is 25-40% in metal mesh 13. |
