A method for manufacturing a disposable worn article including the steps of: carrying a continuous sheet (W1) continuous in a carrying direction (X1) placing elastic members (F3), continuous in the carrying direction of the continuous sheet, on the continuous sheet with the continuous elastic members stretched placing discontinuous sheets (W2), each of which has a predetermined length, on the continuous sheet intermittently and successively in the carrying direction so that the continuous elastic members are sandwiched between the discontinuous sheets and the continuous sheet and carrying out a first joining step in which, in an area where each of the discontinuous sheets is placed, the continuous sheet, each of the discontinuous sheets, and the continuous elastic members are joined to one another, intermittently in the carrying direction, along first joining portions (32A, 32C) extending in a width direction (Y) crossing the carrying direction.
