PROBLEM TO BE SOLVED: To provide a heat insulating composite tile which is manufactured by arranging a heat insulating material formed of a foam resin in a hollow portion of a tile main body, wherein the tile is prevented from cracking at the tile main body due to expanding pressure of a resin liquid injected into the hollow portion, to thereby reduce a percent defective of the product, and to provide a method of manufacturing the heat insulating composite tile. SOLUTION: According to the method, a first foam resin 2 is arranged in the hollow portion 1a of the tile main body 1, and a raw material of a second foam resin 3 is fed into a space between the first foam resin 2 and an inner surface of the hollow portion 1a, followed by expanding the raw materia. The expanding pressure of the raw material of the second foam resin expanded in the hollow portion 1a is exerted not only on the inner surface of the tile main body 1 but also on the first foam resin 2. In this manner not only by dispersing the pressure of the second foam resin but also by absorbing the expanding pressure of the second foam resin by the first foam resin 2, the expanding pressure exerted on the tile main body 1 is eased, to thereby prevent cracking at the tile main body 1.
