A manufacturing method of a mono-polar electrode is provided, wherein the mono-polar electrode can minimize the size of the apparatus with respect to capacity of the apparatus, obtain a long service lifetime, and secure high efficiency and stability when the mono-polar electrode is applied to a sodium hypochlorite generating apparatus. A manufacturing method of a mono-polar electrode comprises: a first step of fabricating a matrix using titanium; a second step of mixing ruthenium(Ru) chloride and tantalum(Ta) chloride in a molar ratio range of 1:1 to 10:1 with a solvent at least once to prepare a solution in a concentration range of 0.1 to 0.5M, and dispersing the solution to prepare a coating solution; a third step of brushing the coating solution onto the matrix to coat the coating solution on the matrix; a fourth step of drying the coated matrix, and subjecting the dried matrix to first heat treatment; and a fifth step of subjecting the coated matrix to second heat treatment to manufacture a mono-polar electrode, wherein the third and fourth steps are sequentially performed at least once, the second heat treatment is conducted at a temperature higher than that of the first heat treatment, and the manufactured electrode comprises 3 to 16 wt.% of ruthenium, 5 to 45 wt.% of titanium, and 51 to 79 wt.% of tantalum.
