<p>PURPOSE: A steering wheel having a heating element is provided to enable some heating lines to be continuously heated even if the other heating lines become short since a heating element comprises a plurality of heating lines. CONSTITUTION: A steering wheel having a heating element comprises a rim(130). A plurality of heating elements are formed on the rim. The heating elements are heated by the power supply of the rim. Each heating element is applied to the surface of the rim as conductive paste. If each heating element is electrically serially connected to the surface of the rim, each heating element is formed so that an electrical resistance value a unit area becomes greater from the inner diameter to the outer diameter of the rim. If each heating element is electrically parallely connected to the surface of the rim, each heating element is formed so that an electrical resistance value a unit area becomes less from the inner diameter to the outer diameter of the rim.</p> |
