The helical broach forms a twisted groove of a predetermined lead on the inner periphery of a machined hole of a workpiece by the plurality of cutting edges. The plurality of cutting edges on the tip side of the broach body in the plurality of cutting edges are made as outer-diameter finishing blades while the plurality of cutting edges on the rear-end side of the broach body are made as tooth-thickness finishing blades. The tooth-thickness finishing blade 7BB is located closest to the rear-end side of the broach body in the plurality of tooth-thickness finishing blades 7B on the rear-end side of the broach body and is formed with a guide blade 13 instead of a cutting blade 9 at the intersecting ridge part between a rake face 5A and a side face facing circumferential one side of the same.
