An information notification apparatus includes a first reception unit that receives a first state change notification indicating that the operating state of an electrical appliance has changed to a first state, a transmission unit that transmits a state notification indicating that the operating state of the electrical appliance is the first state to an information terminal, and a second reception unit that receives an acknowledgement notification. The first reception unit further receives a second state change notification indicating that the electrical appliance has been changed to a second state from the electrical apparatus. The transmission unit calculates a correlation value for each of information terminals and transmits the state notification to an information terminal having a calculated correlation value higher than a threshold value, the correlation value indicating a degree of likelihood that the owner of the information terminal has performed an operation corresponding to the second operating state.
