[Problem] The purpose is to transport the fiber assembly in a more stable state to manufacture a sheet member.[Solution] A method of manufacturing a sheet member, which is a method of manufacturing a sheet member (70) for absorbent articles having a fabric (40) and a fiber assembly (50) in a state intertwined with the fabric (40), It is characterized in that it has a step of arranging the fiber assembly (50) on at least one surface side of the continuous fabric (40), and after the step of arranging, while conveying the fabric (40) and the fiber assembly (50), the entanglement step of jetting fluid toward the fabric (40) and the fiber assembly (50) to make the fiber assembly (50) and the fabric (40) entangle, in the fabric (40) and the fiber The CD direction of the assembly (50) orthogonal to the conveying direction, and the maximum length (W50) of the fiber assembly (50) is equal to or less than the length (W40) of the fabric (40).[課題]目的在將纖維集合體以更穩定的狀態進行搬送來製造薄片構件。[解決手段]一種薄片構件的製造方法，係具有織物(40)、以及和前述織物(40)交絡的狀態的纖維集合體(50)之吸收性物品用的薄片構件(70)的製造方法，其特徵為，具有：在連續的前述織物(40)的至少一方的面側配置前述纖維集合體(50)的配置步驟、以及前述配置步驟之後，邊搬送前述織物(40)及前述纖維集合體(50)，邊朝向前述織物(40)及前述纖維集合體(50)噴射流體，讓前述纖維集合體(50)和前述織物(40)交絡的交絡步驟，在前述織物(40)及前述纖維集合體(50)與搬送方向正交的CD方向，前述纖維集合體(50)的最大長度(W50)為前述織物(40)的長度(W40)以下。
