PROBLEM TO BE SOLVED: To provide a sealed container whose lid is not made of a polycarbonate that may have a harmful influence on human health, and which is sealed while retaining transparency and heat resistance. SOLUTION: The sealed container 10 has a dome lid 2 which is heat-sealed to be easily unsealed. The dome lid 2 is made of a mixture of a polybutylene terephthalate resin copolymer and a polyethylene terephthalate resin homopolymer or polyethylene terephthalate resin copolymer. The polybutylene terephthalate resin copolymer is a copolymer composed of a terephthalic acid component, a tetramethylene glycol component, a polyvalent carboxylic acid component, and a polyvalent alcohol component. The polyethylene terephthalate resin homopolymer is composed of terephthalic acid and an ethylene glycol component. The polyethylene terephthalate resin copolymer is composed of a copolymer composed of: terephthalic acid component and an ethylene glycol component, or 1,4-cyclohexanedimethanol component, a polyvalent carboxylic acid component; and a polyvalent alcohol component.
