A carbon member that can be used favorably as a battery member of a redox flow battery or a fuel cell, wherein the carbon member is obtained by welding, into a single integrated body: a first layer which includes 100 parts by mass of a first resin composition containing a polyolefin-based resin and having a melt flow rate of 0.01 to 10 g/10 min, and 100 to 1,000 parts by mass of a first carbonaceous material; a second layer which includes 100 parts by mass of a second resin composition containing a polyolefin-based resin, having a melt flow rate of 5 to 1,000 g/10 min that is greater than that of the first resin composition, and having a melting point that is 80°C or higher, but is at least 10°C lower than that of the first resin composition, and 100 to 1,000 parts by mass of a second carbonaceous material; and a third layer, which is disposed facing the first layer with the second layer interposed therebetween, and is formed from a porous carbon material having a bulk density of 60 to 800 kg/m 3 . |
