According to an embodiment of the present invention, provided are a method for manufacturing a roller mold having a cutting blade to accurately cut a circular plate with a pattern and a roller mold having a cutting blade manufactured thereby. The method for manufacturing a roller mold having a cutting blade comprises the following steps of: allowing a base pattern to be cut to protrude from the outer circumferential surface of a cylindrical roller with a 3D metal printing method; and forming a cutting blade by machining the base pattern. 본 발명의 일실시예는 원판으로부터 정확하게 패턴을 커팅할 수 있는 커팅날이 형성된 롤러 금형의 제조방법 및 이에 의해 제조되는 커팅날이 형성된 롤러 금형를 제공한다. 여기서, 커팅날이 형성된 롤러 금형의 제조방법은 원기둥 형상의 롤러의 외주면에 커팅하고자 하는 형상의 베이스 패턴이 3D 금속 프린팅 방법으로 돌출 형성되는 단계, 그리고 베이스 패턴이 기계 가공되어 커팅날로 형성되는 단계를 포함한다.
