1. A joining device comprising:
a fixing part that fixes a first metal member to a mounting platform;
a measuring part that measures a height from a surface of the mounting platform to a surface, into which a rotating tool is inserted, of the first metal member near a joint portion, which serves as a part for joining formed by the first metal member and a second metal member placed in a positional relationship for joining by abutting or overlapping, and obtains measured value or values;
a setting part that is configured to set a height position of the rotating tool based on the measured value or values obtained by the measuring part; and
a friction stir body that relatively moves the turning rotating tool along the joint portion based on the height position.
