PROBLEM TO BE SOLVED: To provide a cooker having a seal structure excellent in sealing property and difficult to fix. SOLUTION: The cooker comprises a top plate 2 covering over a product body 1, frames 3 and 4 fixing the periphery of the top plate 2, and a seal member 6 sealing the clearance between the frames 3 and 4 and a cabinet 7 storing the product body 1. As the seal member 6, a foamed material consisting of urethane or polyisobutylene is used. According to this, since the urethane and polyisobutylene used as the foamed material are excellent in characteristic to compression permanet distortion and have a chemical structure hardly causing hydrogen bonding, they show excellent characteristic to fixation. Therefore, the cooker can have a seal structure excellent in sealing property and difficult to fix. COPYRIGHT: (C)2007,JPO&INPIT
