It is possible to provide a positive electrode current collector for lead accumulator capable of improving service life of a lead accumulator and a lead accumulator having the positive electrode current collector. The positive electrode current collector for lead accumulator includes a current collector base made of titanium or a titanium alloy and having a surface covered with a tin dioxide. In the X-ray diffraction pattern, the half-value width of the largest intensity among peaks of the tin dioxide is 1 degrees of below.
