PROBLEM TO BE SOLVED : To provide a stone material coated board in which the layer of a stone material is easily formed, the whole thickness of which can be uniformly reduced, which is light and is hardly broken, and which exhibits excellent far infrared light effect and negative ion effect, and to provide a stone material coated board thermal appliance provided with the stone material coated board and a bedrock bathing apparatus provided with the stone material coated board thermal appliance. SOLUTION : A stone material coating material is obtained by blending 45-75 mass% inorganic material composed essentially of silica and alumina and containing a rare earth mineral and/or far-infrared radiation material and a functional material, 10-40 mass% specific acrylic emulsion resin, 7-15 mass% additive containing methyl cellulose, ethylene glycol and a plasticizer, and 8-20 mass% water. The stone material coating material is applied to a metal made or synthetic resin made board to obtain the stone material coated board. A reclining type foldable bedrock bath seat chair 1 is structured by arranging the stone material coated board thermal appliances 5, 5, 5 formed by providing a heater to the lower side of the stone material coated board on a foot placing part 2, a buttock placing part 3 and the center part of a back rest placing part 4.
