PROBLEM TO BE SOLVED: To provide a bearing seat for a ball joint, capable of improving durability and yield in manufacturing. SOLUTION: The ball joint 100 includes a ball seat 130 as the bearing seat for rotatably and slidably supporting a ball part 113 of a ball stud 110 while bearing the load of the ball part 113. The ball seat 130 includes a first bearing part 131 to get in contact with the ball part 113 of the ball stud 110 in a slidable state, and a second bearing part 140 to house the first bearing part 131. The first bearing part 131 is formed in a roughly cylindrical form of which outer diameter and inner diameter gradually decrease from an upper end part downward, and it is composed of PEEK resin having higher abrasion resistance than material composing the second bearing part 140. The second bearing member 140 is formed in a roughly cylindrical form, and it is composed of POM resin that is easier to deform than the material composing the first bearing part 131.
