1. A method for producing a polymer member having a polymer coating provided on a surface of a polymer shaped object, the method comprising:
curing a curable composition comprising a plurality of organic compounds having functional groups by irradiating the curable composition with energy rays, wherein some of the functional groups react upon being irradiated with the energy rays to form the polymer shaped object, and wherein some of the functional groups in the polymer shaped object are not reacted by the curing;
after the curing, forming the polymer coating on the polymer shaped object; and
after forming the polymer coating, performing a post-curing by irradiating the polymer shaped object through the polymer coating with additional energy rays to subject the polymer shaped object to additional curing by reacting at least some of the unreacted functional groups,
wherein the post-curing is performed so that the polymer shaped object, after being subjected to the post-curing, has a lower surface energy than a surface energy of the polymer coating.
