An ultrasonic module includes a reception circuit adapted to receive a reception signal from an ultrasonic device, which receives an ultrasonic wave, to generate an echo signal, switching power supplies driven with a predetermined switching cycle, and adapted to supply the reception circuit with electrical power, and a phasing addition circuit adapted to perform an addition process on a first echo signal output when driving the reception circuit at a first drive timing in the switching cycle, and a second echo signal output when driving the reception circuit at a second drive timing delayed as much as a half cycle of a switching noise in the switching power supplies from the first drive timing.
