PROBLEM TO BE SOLVED: To solve the problem that a conventional cooker with an opening of a temperature detecting means provided on a top plate center by post- processing is weak in strength, and the top plate is likely to be broken by an impact to the top plate. SOLUTION: The strength of the top plate 5 is improved by joining a reinforcing body 6 in a periphery of the opening 5 provided on the top plate 2, and a temperature of a heated object is accurately measured by exposing the temperature detecting means 3. |
