Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a ball valve which can reliably prevent the simultaneous rotation of a ball seat and a ball through a handle operation by suppressing an increase in processing time. SOLUTION: In the ball valve, a body 2 is formed of hard material like stainless steel, a ball seat 4 is formed of a relatively soft material like fluororesin, and in a ball seat receiving surface 13 of the body 2 made by the hard material, a projection 18 capable of biting into the ball seat 4 is formed.
