The present disclosure relates to a powdery food including a foodstuff containing insoluble dietary fibers including an insoluble dietary fiber localized site. The powdery food has insoluble dietary fiber content of 5 mass % or more by dry mass, and the number average particle size of particles in the powdery food after ultrasonication measured by a laser diffraction particle size distribution analyzer with ethanol is below 30 μm. The powdery food has at least one of N (α/β) of 0.40 or more, where α is a particle number having unevenness degree of 0.6 or less and circularity degree of 0.2 or less and β is a particle number having unevenness degree of 0.6 or more and circularity degree of 0.2 or less, and a regression coefficient a of regression line y=ax+b determined by a least squares method of above 0.35.
