The conveying device has a receiving surface that comes into contact with a first sheet-like object that has one side edge in a wavy shape and is continuous in the conveying direction, and opens to the receiving surface and extends downstream in the conveying direction of the first sheet-like object. A conveying part that defines an inclined slit part for sucking the convex part of one side edge of the wave shape extending obliquely so as to be displaced from the proximal side to the distal side of the convex part, and a convex part in the inclined slit part by suction And a box that defines a suction space for setting the inclined slit portion to a negative pressure.搬送装置は一方の側縁が波形状で搬送方向に連続した第１シート状物に接する受け面を有し、受け面に開口すると共に、第１シート状物の搬送方向の下流側に延びるに従い凸部の基端側から先端側に変位するように斜めに延び波形状の一方の側縁の凸部を吸引するための傾斜スリット部を定義する搬送部と、吸引により傾斜スリット部内に凸部が入り込むように、傾斜スリット部を負圧にするための吸引空間を定義する箱と、を備える。
