PROBLEM TO BE SOLVED: To provide a bedrock bathing apparatus by which expenses for foundation work and movement are reduced and generation of sufficient amount of far infrared rays and negative ions can be achieved. SOLUTION: A honeycomb structure 3 made of aluminum with perforated aluminum plates 2 set above and under itself is integrally mounted on the backside of a natural bedrock 1. A heating part 5 is set on the lower part of the natural bedrock and the aluminum made honeycomb 3 set on the backside thereof. Contents comprising a heater for heating, bamboo charcoal, rock salt, lava, and/or tourmaline, and the rest of loess are set in the heating part 5. As a result, the bedrock may be heated in a short time by using aluminum with high thermal conductivity. By adopting the honeycomb structure 3, the weight of the apparatus may be reduced and high thermal insulation is produced by high air contents. Further, because far infrared rays and negative ions are massively generated from the contents of loess, bamboo charcoal, rock salt, etc., sufficient amount of far infrared rays and negative ions may be secured even if the bedrock has low thickness.
