Abstract
A polymerization initiator, a first polymerizable compound, and a second polymerizable compound are poured into a hollow of a first member (). The first and second polymerizable compounds are copolymerized to produce a second member (). The second member () is produced by forming a first layer () on an inner wall of the first member () and sequentially forming a layer over a precedingly formed layer. To form each layer, the first and second polymerizable compounds are put in the hollow of the first member (), satisfying 1/99≦W2/(W1+W2)≦⅔ when W1 is a weight of the first polymerizable compound, and W2 is a weight of the second polymerizable compound. The first and second polymerizable compounds are mixed such that the value of W2/(W1+W2) increases from the first layer () toward an nth layer.
