PURPOSE: Membrane structure in a microwave oven is provided to reduce a producing cost by minimizing working process through removing bilateral tape. CONSTITUTION: Membrane structure of a microwave oven comprises a sheet metal(100) mounted on outmost end of a membrane by having plural switch units; an adhesive(102) applied to an upper portion of the membrane; a screw hole(103) protruded on the membrane by being attached to a lower portion of the sheet metal; an aluminum sheet(101) formed by a contacting face(101a) of a conductor; a circuit board(105) contacting the contacting face of the aluminum sheet by having plural contacting points(106); an elastic member(104) inserted between the circuit board and the aluminum sheet; and a bilateral tape(107) fixing the circuit board on an upper portion of a control panel(108). Thereby, the membrane structure of the microwave oven reduces producing cost and process.
