Porous titanium having a low contact resistance includes porous titanium body, Au, and a Ti oxide layer (3). Porous titanium includes continuous holes (1) opening on a surface and being connected to inner holes and a skeleton (2). Au adheres to at least an outer skeletal surface (4) of the porous titanium via diffusion bonding to form a network structure. The Ti oxide layer (3) is formed in a clearance between adjacent Au codes (5) of the Au network sticking. The width of an Au code (5) of the Au network is 0.3 to 10 mum at least at one position; and the thickness of the Ti oxide layer (3), which is formed in the clearance between adjacent Au codes (5) of the Au network is 30 to 150 nm.
