Abstract: Provided is a method for manufacturing a spherical particle material in which the particle size distribution is easily controlled. This method has: a granulation step of granulating a raw particle material formed of an inorganic material having a D50 of not larger than 5 μm to form a granulated body; and a spherizing step of heating and melting the granulated body to form the spherical particle material having a D50 larger than a D50 of the raw particle material. A melting method is used as a basic method for manufacturing the spherical particle material having a necessary particle size distribution. The granulated body is used to manufacture the spherical particle material having the necessary particle size distribution by the melting method.
