Abstract: [Problem] To provide a resin particle having excellent heat resistance and flexibility.
[Solution] A resin particle in which a mass loss rate after being immersed in distilled water at 70° C. for 14 days is less than 10%, and in which a mass loss rate after being left in a compost having a composition shown below at 55° C. for 14 days is 90% or more.

Abstract: Resin particles include mother particles containing a biodegradable resin and a plasticizer, in which an amount of a metal element having an ionic valence of 2 or more, obtained by fluorescent X-ray analysis, is 0.002% by mass or more and 2.0% by mass or less with respect to a total amount of the resin particles.
