PURPOSE:To provide a door with radio wave seal device for high frequency heating device which has a high mechanical strength and good radio wave sealing performance. CONSTITUTION:The peripheral part of a door 1 is formed of a groove curved in box to have a U-shaped section, and the groove has a L-shaped part 14 formed by bending the outer wall 2 top end of the groove in U-shape to the inside of the groove. The L-shaped part 14 is formed of a turned part 3 and an inside turned piece 4, and a hole 16 for inserting a metal mold is provided on the bottom surface 15 of the groove opposite to the turned part 3. According to this constitution, since a metal mold 10 is inserted to the hole 16, so that the outer wall 2 can be nipped and bent by the metal mold 10 and another metal mold, and further bent along the surface of the metal mold 10, a door having a strong seal device having a stable dimension and good sealing performance can be provided.
