Abstract
The present invention provides composite particles which are capable of forming an ion exchange membrane with fewer defects and an ion exchange membrane. The composite particles according to the present invention comprise pellets comprising a fluorinated polymer having groups convertible to ion exchange groups, and a powder held on the pellet surface which comprises a polymer, wherein the powder has an average particle diameter of at least 1 μm and at most 1,000 μm, and the ratio of the average particle diameter of the pellets to the average particle diameter of the powder is 2 to 4,500.
