PROBLEM TO BE SOLVED: To solve such a problem that it takes a lot of combustion time at the time of cremation when a tatami floor has a thickness of 1.5 cm or above by using one or a plurality of insulation boards, that a tatami which is manufactured only by a material which is lightweight and has high combustibility has insufficient strength and is simple, and that it appears poor for a tatami which is used when bidding farewell to important blood relationship, relatives, or a friend. SOLUTION: The tatami floor uses one or plurality of insulation boards. A plurality of holes which penetrate the tatami floor in the vertical direction in a state where it has been placed for an improvement in combustibility are provided on the entire surface, and one or a plurality of pieces of corrugated cardboard and the insulation board are fixed by an adhesive or tape, thus an integral tatami floor can be constituted. Combustibility can be improved by providing a plurality of holes which penetrate the tatami floor in the vertical direction in a state where it has been placed for an improvement in combustibility on the entire surface of the insulation board which is an integral insulation board constituted by fixing the corrugated cardboard and the insulation board by the adhesive or the tape.
