Abstract
A device unit is provided with a first heating element, a second heating element configured to generate a heat in an amount smaller than that generated by the first heating element, and a cooler located between the first heating element and the second heating element. The cooler has a coolant flow passage through which a coolant flows, and cooling fins disposed on a first heating element side in the coolant flow passage in a manner as to be substantially in parallel with a flow direction of the coolant, and a fluid resistance of the coolant in the coolant flow passage is smaller on a second heating element side than on the first heating element side.
