Abstract
A threaded joint for pipes including a pin and a box, characterized in that the relationship 0.05 degrees≤θsb−θsp≤2.0 degrees is satisfied, where θsb is an angle of an insertion surface of the female thread on the box side relative to a plane perpendicular to an axis of pipe, and θsp is an angle of an insertion surface of the male thread, which faces the insertion surface of the female thread, on the pin side relative to the plane perpendicular to the axis of pipe.
