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.

Abstract: Organic-inorganic composite particles include: a vinyl polymer that is a polymer of a polymerizable vinyl monomer; and inorganic particles including inorganic oxide and/or inorganic nitride. The thermal conductivity of the inorganic particles is 10 W/(m·K) or more. The inorganic particles are subjected to a surface treatment by acidic phosphoric acid ester having no polymerizable functional group, and by at least one polymerizable compound selected from the group consisting of: carboxylic acid having a polymerizable functional group; acidic phosphoric acid ester having a polymerizable functional group; and lactone having a polymerizable functional group. The polymerizable compound is bonded to the vinyl polymer, and the inorganic particles are unevenly located on surface layers of the organic-inorganic composite particles so that the inorganic particles form one or more layers.
