To provide a photocurable fluorinated polymer composition which has a high curing rate, shows little shrinkage before and after photocuring and requires no post treatment such as heat treatment after photocuring and whereby it is possible to obtain a cured resin excellent in heat resistance and weather resistance. According to the photocurable fluorinated polymer composition comprising a fluorinated polymer (A) containing polymerized units derived from a fluoroolefin and polymerized units derived from an unsaturated monomer having an oxetanyl group or a substituted oxetanyl group, and a photoreaction initiator (B), of the present invention, it is possible to provide a photocurable fluorinated polymer composition which has a high curing rate, shows little shrinkage before and after photocuring and requires no post treatment such as heat treatment after photocuring and whereby it is possible to obtain a cured resin excellent in heat resistance and weather resistance.
