Abstract
A three dimensional molded body which is thin and has an excellent shape-maintainability and a method for manufacturing the three dimensional molded body, which is low in cost and high in productivity. An urethane elastomer (33), which comprises a non-foamable type of a reactive mixture, is integrally pressurized and compressed by an upper portion of a mold and a lower portion thereof, which have predetermined shapes, respectively, when the urethane elastomer is still in a visco-elastic flowing condition during the reaction thereof. The urethane elastomer is transformed into a solid body and is fixed on a back surface of the surface material. A backing material (34) is provided on a whole of a back surface of the urethane elastomer so that the backing material can be completely fixed on the urethane elastomer during the reaction thereof. A natural leather or a synthetic leather is used for the surface material (32). A bag body is integrally molded in three dimensions together with a three dimensional pattern (31).
