In the case of the above-mentioned steering wheel, the heating element is attached around the rim core metal, so the heat from the heating element is absorbed by the rim core metal, making it difficult for the heat to be transmitted to the surface of the rim, resulting in poor efficiency. However, there is no effect unless the heating element is made larger, and the positive temperature coefficient thermistor itself is more expensive than other heating elements, which is a major cost increase factor.
