PURPOSE: A cooling fin for magnetron is provided to improve cooling efficiency of anode by broadening much more contact area of cooling fluid and anode adding air guide at predetermined position of cooling fin, to improve total efficiency of magnetron because cooling efficiency is in proportion to magnetic power, to reduce fluid noise by making fluid flow smoothly. CONSTITUTION: A plane part(41) has vent hole(42) so that anode(5) is penetrated at center and folding part(43) of predetermined height along with edge of the vent hole(42). Pins(44,45) are contacted with lower yoke being united with both side of plane part. The first air guide(71) is formed to be opposite mutually in both direction against cooling fluid input part(50) of plane part(41), and guides to diffuse cooling fluid that is flew in plane part to front of peripheral surface of anode(5). The more it goes from front to rear of plane part, the more angle of slope is broadened gradually toward both side of plane part from central part of front, rear direction of plane part. The second air guide(73) is formed to be opposite mutually against cooling fluid output part(60) of plane part, and guides to diffuse cooling fluid that is flew out plane part to rear of peripheral surface of anode. The more it goes from front to rear of plane part(41), the more angle of slope is concentrated gradually toward central part of front, rear direction of plane part(41) from both side of plane part.
