A multi-jointed robot is provided, which is intended for a reduction in power consumption. The multi-jointed robot includes: a trunk part (3) that is rotatable around a first shaft (11); a base-side arm portion (4) that is rotatable around a second shaft (12), which extends in a direction perpendicular to the first shaft (11), with respect to the trunk portion (3); and a tip-side arm portion (5) that is rotatable around a third shaft (13), which extends in a direction parallel to the second shaft (12), with respect to the base-side arm portion (4). Each of the transmission mechanisms (7) drive-connected with the first shaft (11) and the second shaft (12) is a combination of a motor and a reduction gear with a smaller reduction gear ratio than the transmission mechanism (7) that is drive-connected with the third shaft (13).
