To provide an improved conveyor chain, which can convey even a conveying object having high center of gravity at high speed without felling it down in a curved conveying section. A conveyor chain according to the present invention has a plurality of links ( 10 ) arranged in rows. Each of the links includes a top plate ( 11 ) having a flat top surface ( 12 ) and a hinge portion ( 13 ) provided on the top plate pin-connected to a hinge portion of a link positioned on the front side and to a hinge portion positioned on the rear side. Edges ( 19, 24 ) adjacent to links positioned on the front and rear sides in the top plate and the hinge portions are composed of curved surfaces. An angle of inclination formed by a flat surface ( 31 ) including a tangential line with respect to the edge and the top surface ( 12 ) of the top plate ( 11 ) is formed to be smaller as it goes from the central axis of said link in its arrangement direction toward a link side.
