Abstract
A method for producing a patterned shaped article includes the steps of disposing on a base surface a retainer having a plurality of particle-retaining spaces; filling the spaces with pre-filling particles having a particle size of not more than 600 .mu.m and easy to remove; removing the pre-filling particles from part of the spaces to form at least one empty space; filling the at least one empty space with shaped article-forming particles; repeating the step of removing the pre-filling particles and the step of filling the shaped article-forming particles until the shaped particle-forming particles are substituted for all the pre-filling particles, the shaped article-forming particles including at least two kinds of particles; removing the retainer to form a pattern course on the base surface; and allowing the pattern course to set into an integral mass.
