An electronic circuit is configured to output an output signal after elapse of a predetermined time from a received trigger signal, and includes an oscillator configured to output a pulse signal having a predetermined oscillation frequency; a counter circuit configured to count the pulse signal from the oscillator upon receiving the trigger signal and to output the output signal in response to a count value reaching a predetermined value; and a trimming circuit including a plurality of trimming elements which includes a cuttable conductive part and configured to output a selection signal corresponding to a trimming element having a cut conductive part. In the trimming circuit, the trimming element, which corresponds to the oscillation frequency of the pulse signal output from the oscillator among the plurality of trimming elements, is cut, and the counter circuit is configured to set the predetermined value according to the selection signal.
