A reception field detection apparatus includes a field intensity detection circuit, a correction value setting circuit, an adder, and a first converter. The field intensity detector generates a first digital signal representing a value corresponding to the signal intensity of a received signal. The correction value setting circuit generates a second digital signal representing the correction value of the signal intensity of the received signal in accordance with setting. The adder adds the first digital signal from the field intensity detector to the second digital signal from the correction value setting circuit to generate a third digital signal. The first converter generates a fourth digital signal representing a corrected reception field intensity on the basis of the third digital signal from the adder.
