PROBLEM TO BE SOLVED: To provide a new household appliance which maintains outstanding quality over time, is equipped with a safety valve providing leakproof properties for ensuring the safety of a user during the use for a long period of time, and is used for cooking foods under a pressure. SOLUTION: The household appliance for cooking foods under a pressure includes the safety valve (2) attached for controlling an excess pressure in the inside. The safety valve (2) has a main body (3) equipped with a sheet (4) and a valve member (5), and the sheet (4) and/or the valve member (5) includes at least a part which forms a contact area and is made of a material showing sufficient impermeability, flexibility, and shape-memory properties. When the valve member (5) enters a position for stopping leakage and abuts on the sheet (4) in the contact area, the material assures the leakproof properties for the valve (2) in the contact area.
