PROBLEM TO BE SOLVED: To provide a method for manufacturing an element of a transmission belt for a continuously variable transmission which smoothly transmits the power without causing any bend in the transmission belt, enhances the durability of the transmission belt, and prevents generation of noise. SOLUTION: The method for manufacturing an element 10 of a transmission belt for a continuously variable transmission comprising a saddle portion 11 having inclined portions 14 and 15 in contact with an inner wall of a V-groove pulley and a thickness-reduced portion 16 on a lower side portion, and band holding units 12 and 13 formed on an upper side thereof to fit an endless band punching to form, includes a pressing step of performing thickness adjustment of realizing the uniform thickness at a predetermined element punching position of a plate A other than at least the thickness-reduced portion 16, and thickness reduction of reducing the thickness of a portion of the plate corresponding to the thickness-reduced portion 16, a punching step of punching an overall shape of the element 10 out of the plate, and a pressing step of pressing a peripheral portion of the element 10.
