摘要： The titanium phosphate powder of the present invention includes plate-shaped crystalline particles of titanium phosphate, an average thickness of the plate-shaped crystalline particles is 0.01 μm or more and less than 0.10 μm, and an aspect ratio, which is a value obtained by dividing an average primary particle diameter of the plate-shaped crystalline particles by the average thickness, is 5 or more. In the method for producing a titanium phosphate powder of the present invention, a raw material containing titanium and phosphorus is caused to react by a hydrothermal synthesis method, and when the titanium phosphate powder including plate-shaped crystalline particles of titanium phosphate is produced, a mixture of titanium sulfate and phosphoric acid is used as the raw material.
