Abstract: Resin particles include mother particles containing a biodegradable resin, in which an alkali metal atomic weight A present on a resin particle surface with respect to a total atomic weight present on the resin particle surface, which is measured by an X-ray photoelectron spectroscopy, and an alkali metal atomic weight B present in the resin particles with respect to the total atomic weight present on the resin particles, which is measured by a fluorescent X-ray spectroscopy, satisfy a relationship of 0≤(A/B)

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.
