A semi-finished suspension ( 55 ) is used for manufacturing a head suspension ( 11 ) for a disk drive. The semi-finished suspension includes a base plate ( 37 ), a rigid part ( 27 ) solidly joined with the base plate through a bridge ( 57 ), and a protrusion being the bridge protruding from one of a base plate and rigid part and having a positioning hole ( 63 ) formed through the protrusion of the bridge. This positioning hole is aligned with a positioning hole ( 51 ) formed through part of a flexure ( 41 ).
