An apparatus for manufacturing an article including an absorbent body includes: first and second rolls R1 and R2, in cooperation with each other, for trimming a continuous laminate W2 to be the absorbent body so as to successively form the narrowed portions along the continuous laminate W2; a third roll R3 for rotating in contact with the second roll R2 to receive the continuous laminate W2 from the second roll R2; and a separating cutter C for successively severing the continuous laminate W2 being carried by the third roll R3 into units of individual articles, thereby obtaining the absorbent body.
