In a case where the presence probability of the foreign object is smaller than a threshold, the power transmission apparatus transmits information for use in identification of the presence probability of the foreign object and information about a request for a process related to reacquisition of a parameter to be used to determine a presence probability of the foreign object, and in a case where the presence probability of the foreign object is greater than the threshold, the power transmission apparatus transmits information for use in identification of the presence probability of the foreign object without the information about a request for the process related to reacquisition of the parameter.
