An object of the present invention is to provide a powder of high-purity 1,4-cyclohexanedicarboxylic acid with excellent powder flowability. The invention provides a powder of high-purity 1,4-cyclohexanedicarboxylic acid having particle size distributions (volume basis) such that D
10
is within a range of 5 to 55 μm, D
50
is within a range of 40 to 200 μm, and D
90
is within a range of 170 to 800 μm; and having an aerated bulk density of 0.4 to 0.8 g/cm
3
, a packed bulk density of 0.5 to 1.0 g/cm
3
, and a compressibility of 10 to 23%.
