  "textContent": "An injection control device includes: a boost controller charging a boost capacitor by performing a boost switching control of a boost switch, and supplying a boost power from a battery power source; and a boost voltage monitor monitors a boost voltage. The boost controller measures a number of times of when the boost voltage becomes equal to or higher than a predetermined value due to a boost current flowing into the boost capacitor, causing a jump of the boost voltage during a time between a start and stop of boosting, and determines deterioration of the boost capacitor by comparing the measured number of times (i.e., the number of jumps) with a predetermined number of times.",
