A milling cutter is provided to obtain the light of an aluminum milling cutter by making a main body member of first material having light specific gravity and obtain the rigidity of a steel milling cutter by making a cutting part of second material having heavy specific gravity. A milling cutter(1) comprises a main body member(100) and a cutting part(200). The main body member is made of aluminum or magnesium alloy. A first inclined plane is formed in the main body member. The cutting part is coupled to the main body member and is made of steel and has one or more cutting tips(220). A second inclined plane corresponding to the first inclined plane is formed in the cutting part.
