Zusammenfassung:	The present disclosure is directed to a powder of fine spherical strontium titanate particles with a primary particle having an average primary particle size equal to or less than 50 nm, a circularity greater than or equal to 0.8, and a lattice constant equal to or less than 3.925 Å. The powder of fine strontium titanate particles has high crystallinity, a low moisture content, and a good particle size distribution, so that a composite film having homogeneously distributed particles without suffering resin film deterioration can be provided.
