A tubular member includes a resin layer containing a thermoplastic resin and a conductive material, and the resin layer forming a sea part in which the thermoplastic resin becomes a matrix phase, wherein an area ratio of the sea part to a portion in a range of 5 μm respectively to a front surface portion side and a rear surface portion side with a central portion of the resin layer in a thickness direction as a center is greater by 3% to 15% than a greater area ratio between an area ratio of the sea part to a portion in a range of 10 μm from a front surface portion of the resin layer in the thickness direction and an area ratio of the sea part to a portion in a range of 10 μm from a rear surface portion in the thickness direction.
