Abstract: To provide polyamide-based resin foam particles which enable provision of a polyamide-based resin foam particle molding that is excellent in moldability.SOLUTION: Polyamide-based resin foam particles have such a crystal structure that a polyamide-based resin inherent peak and a high temperature peak having a top temperature on a higher temperature side than the top temperature of the inherent peak appear in a DSC curve, in which heat of fusion at the high temperature peak is 5 J/g or more and 50 J/g or less, and a coefficient of variation of the heat of fusion at the high temperature peak is 20% or less. A method for producing polyamide-based resin foam particles includes: a foaming agent application step of impregnating a polyamide-based resin dispersed in an aqueous dispersion medium in a closed container with a foaming agent, to obtain foamable polyamide-based resin particles; and a foaming step of emitting the foamable polyamide-based resin particles from the closed container under a pressure lower than the pressure in the closed container, to foam the particles. In the foaming step, temperature-rise control of raising the temperature in the closed container to 0.3°C or higher and 1.5°C or lower per 10 minutes is performed when the foamable polyamide-based resin particles are emitted from the closed container in the foaming step.SELECTED DRAWING: Figure 1
