PROBLEM TO BE SOLVED: To solve the problem that, in a conventional heating cooker, temperature signals of a temperature detector are differentiated and then a moving average of the differentiated temperature signals is taken, easily causing an error to a boiling judgement temperature when noises are overlapped. SOLUTION: The temperature detector 23 detects the temperature of the bottom of a cooking container 21. A moving average means 26 takes a moving average of temperature data for consecutive two or more times from the temperature detector 23. A temperature differentiating means 27 differentiates the moving average value to calculate a variation in temperature. A boiling detecting means 28 detects the boiling from a fact that the differentiated value becomes a prescribed value or below, making a heating cooker capable of detecting the boiling of a cooked object.
