Abstract: In manufacturing a heating toilet seat (40), a heater (72) is inserted into heater holding grooves (64) in a support base material (60), a heat-transfer sheet (74) is provided to cover the heater (72) and the support base material (60), and an adhesive sheet (76) is used to bond a heater unit (70) to the upper surface (62) of the support base material (60). Then a seat body (50) is laminatingly formed on the heat-transfer sheet (74) by injection molding. The heat-transfer sheet (74) covers irregularities of the heater (72) and is flush with the upper surface (62) of the support base material (60) to provide a smooth surface. Accordingly, a fused resin smoothly flows at the time of injection molding of the heater toilet seat (40), and the heater (72) will not be displaced or moved to one side even under high injection pressure.

Abstract translation: 在制造加热马桶座（40）时，将加热器（72）插入到支撑基材（60）中的加热器保持槽（64）中，设置传热片（74）以覆盖加热器（72） 和支撑基材（60）和粘合片（76）用于将加热器单元（70）接合到支撑基材（60）的上表面（62）。 然后，通过注射成型在传热片（74）上层压地形成座体（50）。 传热片（74）覆盖加热器（72）的不规则部分，并且与支撑基材（60）的上表面（62）齐平，以提供光滑的表面。 因此，在加热器马桶座（40）的注射成型时，熔融树脂平滑地流动，即使在高注射压力下，加热器（72）也不会移动或移动到一侧。
