HEATER ELEMENT AND STEERING WHEEL

摘要

PROBLEM TO BE SOLVED: To provide a heater element capable of preventing the appearance of an arrangement portion from being reduced even if the heater element is arranged while being bent in a product portion such as a ring part of a steering wheel.SOLUTION: A cord-shaped heater 1 in a predetermined pattern shape disposed between two substrates 10A and 10B each formed from a foamed polyurethane resin is disposed so as to be held between the two substrates 10A and 10B by heating compression while interposing an adhesive for mutually adhering the substrates between the substrates. For a heater element 20, a thickness dimension tH0 after the heating compression is set to exceed 1.0 mm. A weight per unit area in a non-arrangement part 22 where the cord-shaped heater is not arranged, is settled within a range of 0.016 to 0.040 g/cmexcluding the weight for the adhesive.
