The invention relates to a device and a method for determining accumulated lead errors of a ball screw shaft. The device (S1) for determining accumulated lead errors of a ball screw shaft comprises a fixing supporting platform (1) by which the ball screw shaft (W) to be determined is fixed and cannot rotate, a ball contact (5) which abuts against a thread groove of the ball screw shaft to be determined, a ball contact sliding mechanism (4) which enables the ball contact to perform reciprocating motion along the direction orthogonal to a shaft center of the ball screw shaft to be determined and to abuts against the thread groove under the effect of a specified pressing force, a position detection sliding mechanism (3) which enables the ball contact sliding mechanism to perform reciprocating motion horizontally in parallelism with the shaft center, a positioning reciprocating sliding mechanism which enables the position detection sliding mechanism to perform reciprocating motion in the thread part of the ball s
