Abrégé

Although a means for suppressing deformation of a pin seal has been proposed in a related art, a method of solving a problem caused by deformation on a box side has not been proposed. The present invention provides a threaded joint for pipes, characterized in that the relationship 0.05 degrees ‰¤ ¸ sb - ¸ sp ‰¤ 2.0 degrees is satisfied, where ¸ sb is an angle of an insertion surface 21 of the female thread on the box 1 side relative to a plane perpendicular to an axis of pipe, and ¸ sp is an angle of an insertion surface 20 of the male thread, which faces the insertion surface 21 of the female thread, on the pin 3 side relative to the plane perpendicular to the axis of pipe.
