Abstract
A core-shell particle including a core containing a perfluoropolymer and a shell containing a non-fluorine resin, the core having a periphery coated with the non-fluorine resin at a coverage of 90% or more, the perfluoropolymer being a polymer containing a polymerized unit based on a perfluoro monomer in an amount of 90 mol % or more relative to all polymerized units, and the shell having a mass of 50 or less relative to a total mass of the core and the shell of 80. Also disclosed is a method for producing the core-shell particle.
