PURPOSE:To obtain stable electromagnetic transducing characteristics by providing a notch to a flat face inbetween a load arm and folding a connecting part to vary a resonance point thereby attenuating the displacement at the resonance point. CONSTITUTION:The long folded parts 1g are provided to a flat face 1d between a tip and base 1a of the load arm 1 1a in a direction of a ridge 1b formed to the load arm 1, that is, along the ridge 1b at the opposite side of 1 disk. The folded part 1g is formed by notching the flat face 1d of the load arm 1 and providing a long U-shape notch 1e and folding the connecting part 1f to the flat face 1d to the ridge 1b. Thus, the resonance point is varied and the resonance level is attenuated to obtain stable electromagnetic transducing characteristics.
