PROBLEM TO BE SOLVED: To provide a porous titanium alloy in which a porous structure can be formed only by being simply subjected to cooling in a melted state. SOLUTION: The porous titanium alloy has a composition expressed by formula (1): (Ti<SB>a</SB>M1<SB>b</SB>M2<SB>c</SB>M3<SB>d</SB>)<SB>x</SB>(Ti<SB>e</SB>R1<SB>f</SB>)<SB>1-x</SB>; wherein, M1 is V, Cr, Co, Mn, Fe, Ni, Zr or Y; M2 is Cu, Pd, Ag, Pt or Au; M3 is Al, Zn, Ga, Cd, In, Sn, Sb, Hg, Tl, Pb, Bi or Po; R1 is Nb, Mo, Tc, Ru, Rh, Hf, Ta, W, Re, Os or Ir; and a=100-(b+c+d), b=1 to 30, C=1 to 30, d=2 to 20, e=100-f, f=10 to 50, and x=0.1 to 0.7 (in the formula, a, b, c, d, e and f are atomic percent).
