(57) Abstract: The present invention provides spacer particles having a small variation in compression elastic modulus and elastic recovery ratio among particles, and a small variation among manufacturing batches. Kind Code: A1 Abstract: Laminated fine particles comprising core particles and a polyorganosiloxane coating layer on the surface of the core particles, wherein the polyorganosiloxane coating layer comprises two or more kinds of organosilicon compounds represented by the following formula (1). A mixture of a hydrolyzate and a polycondensate, wherein the mixture is composed of two or more kinds of organic silicons having different decomposition temperatures of hydrocarbon groups (R 1 -Si groups) directly bonded to silicon atoms of the organic silicon compound. Polyorganosiloxane-coated elastic fine particles, which are a mixture of compounds. R 1 n Si (OR 2 ) 4-n (1) (wherein, R 1 represents a hydrocarbon group having 1 to 10 carbon atoms selected from a substituted or unsubstituted hydrocarbon group, R 2 represents a hydrogen atom, Represents an alkyl group having 1 to 5 carbon atoms, an acyl group having 2 to 5 carbon atoms, and n is an integer of 1 to 3) |
