Abstract:
There is provided a novel polyamide particles having an approximately spherical outer shape, which are spongy particles having through-holes in an outer surface part and closed voids in an inside part. The polyamide particles can be produced by dissolving a polyamide in a cyclic amide with heating to obtain a homogeneous solution and then cooling the solution.
