PROBLEM TO BE SOLVED: To provide a balance weight for a flywheel that can eliminate a rotational unbalance test of a flywheel after die-cast molding, and machining for corrective balancing. SOLUTION: The balance weight 20 is used for a magnet 2 on the flywheel 1 in a high tension magnet igniter. The balance weight 20 is manufactured by the lamination of laminate members 21 stamped from a steel plate or manufactured by integral molding of a sintered alloy. The balance weight 20 is provided in advance with an adjusting hole 26 for corrective balancing of rotational unbalance, and balancing is performed by adjusting the depth of the adjusting hole 26 in manufacturing.
