PROBLEM TO BE SOLVED: To provide a resin particle obtained by using a fluid in a liquid state or a supercritical state and having a sufficiently narrow particle size distribution, and a method for manufacturing the resin particle obtained by using a fluid in a liquid state or a supercritical state and having a sufficiently narrow particle size distribution.SOLUTION: A resin particle (C) is formed by fixing or coating fine particles (A) to the surface of a resin particle (B) containing a resin (b). The degree of swelling of the fine particle (A) by carbon dioxide (X) in a liquid state or a supercritical state is 16% or less at a temperature less than the glass transition temperature or the melting point of the fine particle (A). A crystalline resin (a1) having a specified composition is used as the fine particle (A). |
