A determining apparatus ensures an assurance value of reliability in the determination result for determining the correct tag. A signal receiving unit 121 receives a signal transmitted by the tag (the communication apparatus), a plurality of times. An identification acquiring unit 122 acquires identification data of the tag based on the received signal. The reception counting unit 123 counts a number of reception times the signal is received for each tag. The apparatus determining unit 132 determines that the tag having the more number of reception times as the correct tag (the communication partner) when the difference in the number of reception times is greater than or equal to the times difference threshold.
