Zusammenfassung:	In a high-density mounting small power conversion device in which a distance between a bus bar and a drive circuit board in reduced, the driving circuit board receives a blast of heat from the bus bar. Heat buildup due to self-heating of the drive circuit board is generated by mounting a capacitor on the upper side in close proximity to the drive circuit board. These factors cause a problem such as a malfunction or life reduction of the drive circuit board. To cope with this, in a cooler for cooling a 2in1 power module, a plurality of 2in1 power modules are arranged side by side in the vertical direction, which is the longitudinal direction of the 2in1 power modules, bus bars connected to the 2in1 power modules are arranged on one sides in the transverse direction of the 2in1 power modules, and control signal lines connected to the 2in1 power modules are arranged, together with a drive circuit board for sending a control signal to the control signal lines, on the opposite sides of the one sides in the transverse direction of the 2in1 power modules.
