PROBLEM TO BE SOLVED: To provide a combustion control device capable of accurately grasping the end timing of discharging noise by only software processing. SOLUTION: An electronic control circuit is constituted of: a first means for storing a detection signal SG(N); a second means ST5 for specifying a rapid increase section based on a signal level S of the detection signal SG stored in the first means and its deviation level DIF(N); a third means ST10 for determining whether or not the detection signal SG after finishing the rapid increase section starts to slightly increase, and in the case where the slight increase starts, specifying an end timing of discharging noise by responding to the timing; a fourth means ST13 for determining whether or not the detection signal SG after finishing the rapid increase section starts to decrease, and in the case where the decreasing starts, specifying the end timing of discharging noise by responding to an addition value of the timing and the rapid increase section; and a fifth means for analyzing the detection signal SG after the end timing of the discharging noise specified by the third means ST10 or the fourth means ST13.
