In a magnetic head suspension, a main body region of a flexure substrate is fixed to a load beam part at plural welding points including F/L first and second welding points respectively arranged on distal and proximal sides of a position of a LB bending that reduces a gain of a torsion vibration of the load beam part. In a case where a length of a flat region in the suspension longitudinal direction is represented by F, the flat region extending between an end position on the distal side of the bending at the LB bending position and the F/L first welding point is represented by F, and a length between the F/L first welding point and a supporting arm welding point is represented by D, a condition of 0.02≤F/D≤0.05 is met.
