Disclosed is a polyolefin porous sintered compact that can ensure high water absorption performance, has low pressure loss, and is excellent in durability. SOLUTION: This includes polyolefin particles composed of polyolefin, has a thickness of 0.05 to 1 mm, and has median pore diameters corresponding to 10% cumulative and 90% cumulative from the large diameter side of the cumulative pore distribution. , D10, D90, a polyolefin porous sintered compact having a median pore diameter distribution with a D10 / D90 ratio of 10 or less.
