Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vacuum pump with a rolling bearing for improving the support of a high-speed rotation rotor of the vacuum pump.SOLUTION: The vacuum pump with the rolling bearing includes the rotor and the rolling bearing. The rolling bearing supports the rotor rotationally and includes rolling bodies 32. Each of the bodies 32 has a ball diameter 102, and a ball center 100 of the rolling bodies 32 is located on a pitch circle 104 having a circumference. For improving support for the high-speed rotation rotor, the rolling bearing is fully constituted of only the balls without any support and the sum total of the ball diameter 102 of the supporting balls is approximately 0.85-0.97 times the circumference.
