A heat generating member cooling structure in which a coolant space is formed between a heat releasing surface that is thermally connected to a heat generating member and an opposing surface that is positioned opposite the heat releasing surface, includes a plurality of heat releasing fins that are provided within the coolant space so as to be parallel to one another and stand from the heat releasing surface toward the opposing surface, and an inter-fin passage, through which a coolant flows, formed between every two of the plurality of heat releasing fins that are positioned adjacent to each other.

Heat generating member cooling structure and drive unit

An electronic circuit device includes a lower-side substrate formed with a main circuit; an upper-side substrate formed with a drive control circuit that drivingly controls the main circuit; a support body positionally fixed above the lower-side substrate with resin in a hardened state; and a case having a peripheral portion with an outer surface that has at least a portion of an external lead-out terminal of the drive control circuit and the main circuit thereon, and a substrate storage space that accommodates the lower-side substrate on a side inward from the peripheral portion.
