Abstract
An apparatus can be used for heating a steel sheet. A positive electrode is configured to make contact with a first electrode area of the steel sheet and a negative electrode is configured to make contact with a second electrode area of the steel sheet. A cooling member includes a cooling block configured to make contact with a cooling area adjacent to a third edge parallel to a second direction. The cooling member is configured to radiate heat generated from the steel sheet. The positive electrode, the negative electrode, and the cooling member are arranged on the steel sheet such that the resistance of a path from the positive electrode to the negative electrode through an area with which the cooling member makes contact is higher than the resistance of a path from the positive electrode to the negative electrode through the cooling member.
