Abstract
An ordinary pattern and a liquid repellent pattern are formed on the base paper. The base paper is then impregnated with a thermosetting resin having a characteristic of being repelled by the liquid repellent pattern. A covering layer of the impregnated resin is formed by the thermosetting resin which has not been impregnated into the base paper and remains on the surface of the base paper. As the thermosetting resin for impregnation is repelled by the liquid repellent pattern, the covering layer of the impregnated resin is not formed on the liquid repellent pattern. The covering layer of the impregnated resin is formed so as to be thicker than the liquid repellent pattern. Due to this, a recessed portion is created at the portion where the liquid repellent pattern is formed.
