Abstract: An injection control device executes a current-drive of a fuel injection valve to inject fuel into an engine. The injection control device includes: a drive controller that controls energization by correcting an energization instruction time when injecting the fuel by executing the current-drive of the fuel injection valve; an estimated energization time correction amount calculation unit that calculates an estimated energization time correction amount; and a deterioration determination unit that determines deterioration of the charging capacitor based on a calculated estimated energization time correction amount and the energization time correction amount.
