PROBLEM TO BE SOLVED: To provide a method for producing a titanium or titanium-based alloy filter containing less oxygen, which can decrease an amount of powder to be ground by molding such as pressing, prevent reduction and variation in porosity and which is handled safely and can use fine powder as a raw material of the filter. SOLUTION: A method for producing a titanium or titanium-based alloy filter of the present invention comprises the use of titanium hydride as a raw material, wherein the titanium hydride further has a content of 0.05 to 4% by weight of hydrogen, and titanium hydride powder having a particle size of 50μm to 400μm is used as a raw material; and the titanium hydride is further press-molded and then sintered.
