PROBLEM TO BE SOLVED: To provide a manufacturing method for a disposable diaper, which enables first-fourth elastic members to be precisely fixed across a pair of sheet materials in such a manner as to draw different curved shapes, respectively, and which enables the stable and efficient manufacture of the disposable diaper enhancing the fittedness of each part. SOLUTION: This manufacturing method comprises manufacturing steps for an elastic laminate, that is, a step of applying an adhesive to the pair of sheet materials, a step of oscillating first and second elastic members by making first and second oscillation guides 10 and 20 move forward and backward in the width direction of the sheet material by means of a first cylindrical cam mechanism 1A which is equipped with two driven shafts 13 and 23 and a cylinder 14 with two protrusive streak parts 11 and 12, a step of oscillating third and fourth elastic members by making third and fourth oscillation guides 30 and 40 move forward and backward in the width direction of the sheet material by means of a second cylindrical cam mechanism 1B with a constitution similar to that of the mechanism 1A, and a step of nipping the pair of sheet materials by a pair of nip rolls in a state wherein the first-fourth elastic members are arranged between the sheet materials, after the oscillation of the third and fourth elastic members.
