PROBLEM TO BE SOLVED: To easily suppress unevenness of heating temperature of a member to be heated, particularly, a member to be heated formed in a non-rectangular shape while avoiding a problem of fusing of mutual members to be heated, which is possibly be caused when the members to be heated are electrically heated.SOLUTION: A method for electrically heating a platy member to be heated includes: a step of preparing a plurality of members to be heated; a step of overlapping the members to be heated; a step of attaching a pair of electrodes 11 in a state where the members to be heated are overlapped; and a step of supplying a current between both of the electrodes 11. The total of products S/&rgr; of a cross sectional area S of a predetermined cross section of each member to be heated in the direction orthogonal to the direction of current supply and an inverse number of electric resistivity &rgr; is substantially constant in the direction of the current supply, and a pair of platy fusing preventing members 14 having electric resistivity smaller than that of the members to be heated is interposed to both end portions and between each of the members to be heated so that the end portions of the members 14 opposing with each other are in substantially the same positions as the opposing end portions of the pair of electrodes. |
