Abstract: The present invention enables to provide plate-like titanium pyrophosphate, having both high uniformity in size and specific particle shape, which is expected to be highly useful. The present invention relates to plate-like titanium pyrophosphate having an aspect ratio of 5 or more expressed as a ratio of the in-plane length DPL50 of primary particles, at which the cumulative frequency from the smaller particle size side is 50% in a volume-based cumulative particle size distribution, to the thickness DPT50 of primary particles, at which the cumulative frequency from the smaller particle size side is 50% in a volume-based cumulative particle size distribution (the in-plane length DPL50 of primary particles/the thickness DPT50 of primary particles), wherein the relationship among the particle size D10 of secondary particles, at which the cumulative frequency from the smaller particle size side is 10% in a volume-based cumulative particle size distribution, the particle size D50 of secondary particles, at which the cumulative frequency from the smaller particle size side is 50% in a volume-based cumulative particle size distribution, and the particle size D90 of secondary particles, at which the cumulative frequency from the smaller particle size side is 90% in a volume-based cumulative particle size distribution, satisfies a specific relationship; and a method for producing the same.
