PROBLEM TO BE SOLVED: To attain high load in a ball bearing made of synthetic resin having corrosion resistance. SOLUTION: In the resin ball bearing in which an inner ring 1 and an outer ring 2 are made of synthetic resin and a ball 5 is made of ceramics, a configuration is adopted that maintains the size of the inner and outer rings 1, 2 to be equal to those in a standard ball bearing and sets the diameter of the ball 5 to 68-75% of the radial thickness of the bearing. The resin ball bearing can attain 1.5 times the high load of a conventional ball bearing without deteriorating strength even though rolling faces of the inner and outer rings 1, 2 are made thin.
