PROBLEM TO BE SOLVED: To obtain a barium titanate particulate powder which is free from aggregation and is excellent in dispersibility, and to obtain an economically and industrially advantageous method for manufacturing the barium titanate particulate powder. SOLUTION: The barium titanate particulate powder has an average primary particle diameter of from 10 nm to less than 20 nm, a sphericity of 1.00 to 1.18 and a ratio of the average secondary particle diameter to the average primary particle diameter of from 0.7 to 6.0.
