An elastic plate connected at both ends to a pair of supporting pieces of a supporting portion and connected at center to a member forming a load beam portion functions as a load bending portion, thereby enhancing impact resistance against jumping motion of a magnetic head slider. A balance mass member is mounted on a portion of the member forming the load beam portion positioned on a base-end side than the elastic plate, thereby enhancing impact resistance against clashing motion of the balance mass member while equilibrating mass between tip-end and base-end sides of the load beam portion. A narrowest portion of the supporting portion is positioned, with respect to the suspension lengthwise direction, between a position of a base-end of a concave portion defined the pair of supporting pieces and a position where phantom lines extending from inner side edges of arm areas of the supporting pieces intersect with a longitudinal center line of the suspension, thereby effectively reducing mass of tip-end side of the supporting portion without deteriorating rigidity of the supporting pieces.
