Abstract: Provided are a porous sintered compact suitable for a filter, a power feeder in a polymer electrolyte membrane type water electrolyzer, a current collector in a solid polymer fuel cell and in addition a liquid dispersion plate, especially an ink dispersion plate for an ink jet printer ink and the like. A titanium powder sintered compact made of a plate-like porous compact is obtained by sintering spherical powder made of titanium or a titanium alloy produced by means of a gas atomization method. A void ratio in the range of from 35 to 55% is realized by filling without applying a pressure and sintering without applying a pressure.
