Abstract
An object of the invention is to accurately detect a state of an object to be heated in a cooking vessel and effectively avoid cooking failure. An induction heating section () inductively heats a cooking vessel (). A vibration detecting section () detects a vibration of the cooking vessel () via a top plate (). A vibration waveform extracting section () extracts a vibration waveform of a frequency component having a frequency equal to a predetermined multiplication product of an induction heating frequency, from a waveform of the vibration detected by the vibration detecting section (). A determining section () determines a state of an object to be heated, based on the vibration waveform extracted by the vibration waveform extracting section ().
