The present invention relates to a casting roll of a twin-roll type strip continuous casting device. The casting roll of the twin-roll type strip continuous casting device wherein a plurality of fine grooves are formed on a surface is characterized by a fact that an area rate of ridges, which forms fine grooves on the surface of the casting roll, on an edge part is higher than a middle part; thus improving coagulation efficiency of molten steel in the edge part. Accordingly, the casting roll of the twin-roll type strip continuous casting device is capable of improving a quality of a front surface of a casted piece, and ensures stability for casting by reducing a bulging phenomenon as the molten steel is uniformly coagulated in a widthwise direction.
