の原因とならない。Then, the remaining resin portion 20 corresponding to the central hole portion of the toilet seat is cut at a position indicated by a chain double-dashed line C in the post-processing. Although the cutting direction is the vertical direction for convenience, it may be cut appropriately. At this time, the base material 3 of the heater unit 1 is a sheet or film made of the same material as the molding layers 14 and 19, and therefore is compatible with the molding layers 14 and 19, so that the cut surface 21 of the cutting seat trace of the toilet seat 35 is formed. The streaks of the base material 3 do not remain. Further, since no seam is formed between the molding layers 14 and 19, no urine or sewage enters. The toilet seat 35 has a planar horseshoe-shaped or O-shaped cavity 22 communicating with the inside through the leg rubber insertion hole 18. During heating, the cavity 22 prevents heat from being dissipated to the back surface of the toilet seat due to the air insulation function, and the heat efficiency to the front surface is improved so that electricity is not wasted. Finally, the leg rubber insertion hole 1
Since the leg rubber 49 is watertightly fixed to the No. 8 with an adhesive (not shown), it is possible to prevent urine and sewage from entering the inside of the toilet seat, which does not cause a bad odor.
