A reception circuit includes: an AD converter that outputs digital data in accordance with an input signal; a correction circuit that corrects nonlinearity of the AD converter; and an equalization circuit that equalizes the corrected digital data, wherein the correction circuit includes: a conversion table used to convert digital data output from the AD converter; and a correction amount computation circuit that creates the conversion table from the output data of the AD converter and the output of the equalization circuit. The correction amount computation circuit creates the conversion table so that there is no dependence between the ADC output value of the AD converter and the estimation result by the equalization circuit for the ADC output value.
