Claim Text:
1. A fluorinated copolymer comprising from 40 to 90 mass % of units derived from the following monomer (a), from 2 to 20 mass % of units derived from the following monomer (b), from 2 to 20 mass % of units derived from the following monomer (c), from 2 to 20 mass % of units derived from the following monomer (d) and from 0.1 to 10 mass % of units derived from the following monomer (e), wherein the ratio of units derived from the following monomer (f) to the units derived from the monomer (a) is at most 10 mass ppm: monomer (a): F(CF monomer (b): vinyl chloride, monomer (c): vinylidene chloride, monomer (d): an alkyl (meth)acrylate having a C monomer (e): a monomer having no fluoroalkyl group and having a cross-linkable functional group, monomer (f): F(CF
