Abstract
An injection control device includes: a conversion coefficient setter setting a conversion coefficient for each injection when a fuel injection valve is driven by an electric current to inject fuel from the fuel injection valve; and an area correction unit calculating an energization time correction amount by performing area correction using the conversion coefficient for each injection regardless of whether a drive current of the fuel injection valve has reached a target peak current or not.
