A sealed container such as beverage and food containers having lids sealed by laser beam welding and thermal fusing to impart high applicability to impurities, increase sealability, and increase a joining strength between a container body and a lid. The sealed container comprises the container body (1) having a mouth part (9) and the lid (3) causing a deformation therein when it closes the mouth part (9), producing a fitted portion (4) forming a seam in a pressurized state on the container body (1) by a strain stress, and formed of a plastic material. The fitted portion (4) is thermally fused. |
