PROBLEM TO BE SOLVED: To provide a friction stir device capable of accurately designating a three-dimensional shape of a joining line, a control method for its probe, a control program, a recording medium for recording the program, and to provide a manufacturing method for a joined body. SOLUTION: The friction stir-joining device is provided with the probe, a driving means for the probe, and a control means. The control means calculates an interpolation position vector, an interpolation tangential vector, and an interpolation normal vector, which correspond to the joining line between two measurement points adjacent to each other, with interpolation by using position vectors (P<SB>1</SB>-P<SB>n</SB>) and normal vectors of a plurality of the measurement points (P<SB>1</SB>-P<SB>n</SB>) on the joining line of a workpiece. The control means also calculates control data for deciding a posture of the probe by using the interpolation position vector, the interpolation tangential vector, the interpolation normal vector, and a prescribed angular advance. Consequently, the posture of the probe can be controlled by controlling the driving means with the control data. COPYRIGHT: (C)2006,JPO&NCIPI
