Abstract

The present invention provides vinyl-based resin particles capable of easily smoothing the surface of a thermosetting resin film when the particles are used as a pore-forming material for a thermosetting resin. Specifically, the present invention provides vinyl-based resin particles for use in making a thermosetting resin porous, the particles having a temperature of 230° C. or higher and lower than 300° C. at 10% mass loss when heated at a rate of 10° C./min in an air atmosphere, and the particles having a mass loss percentage of 85 to 100% after being heated at 350° C. for 5 hours in an air atmosphere.
