In a belt for a continuously variable transmission, a first clearance CLNH is defined between a projection and a recess formed on front and rear surfaces of a metal element, and a second clearance CLy is defined between an upper surface of a metal ring assembly and a lower ear surface of the metal element. By setting a relation, CLY>CLNH ensures, that when the metal element has been pitched, the projection and the recess can be first brought into contact with each other, thereby preventing a reduction in durability of the metal ring assembly. If the thickness of the metal ring assembly is represented by TL, and the vertical opening of the ring slot is represented by D, when the value of D/TL exceeds 11/8, the power transmitting efficiency is reduced. Therefore, the reduction in power transmitting efficiency can be prevented while maintaining durability of metal ring assembly by setting D/TL at a smaller value than 11/8.
