Summary:A door for preventing leakage of electromagnetic wave of a microwave oven includes: a front panel (31) forming a front surface of a door; a first contact surface (9) expanded from the circumference of said front panel (31) and retreated backward a cavity (1) of said microwave oven so as to contact an entrance of the cavity (1); a door frame (7) expanded from the circumference of said first contact surface (9) and proceeding to the front surface of said door so as to form a frame (7) of said door; a second contact surface (8) expanded from the circumference of said door frame (7) and retreated backward the cavity (1) so as to contact a frame of the cavity entrance; a choke cavity (321) formed between the door frame (7) and said second contact surface (8); and a slit (32) formed on the circumference of said door fame (7) in a predetermined interval and expanded into the choke cavity (7) in a predetermined length. Thus, leakage of the electromagnetic wave can be prevented due to the slit shape of a predetermined period. Also, various designs can be provided by making the door panel (31) to be attached of detached to/from the door frame (7).
