<P>PROBLEM TO BE SOLVED: To provide a bath tub which can provide stable heat insulating effect with the micro beads evenly dispersed, or which can provide a different local heat characteristic from other areas with micro beads unevenly distributed, if necessary. <P>SOLUTION: The bath tub comprises a bath tub main body 1 made of fiber-reinforced plastic and an inner coat 2 covering the whole inner surface of the bath tub main body 1. The bath tub main body 1 has a base material 3 made of heat-hardening resin, microbeads 4 to be mixed in the base material 3 and a fiber-reinforced material 5 as the components, and to form a tub, these components are sprayed over the inner coat 2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
