A hybrid drive device comprising: an engine rotation transfer member drivably coupled to an internal combustion engine; a rotary electric machine that has a rotor; a rotor rotation transfer member drivably coupled to the rotor; a coupling member drivably coupled to an oil pump; an engagement element that drivably couples the engine rotation transfer member and the rotor rotation transfer member to each other; a first one-way clutch that is disposed between the engine rotation transfer member and the coupling member and that is engaged when rotation of the engine rotation transfer member is higher than rotation of the rotor rotation transfer member; a second one-way clutch that is disposed between the rotor rotation transfer member and the coupling member and that is engaged when rotation of the rotor rotation transfer member is higher than rotation of the engine rotation transfer member; a first power transfer path (Pal) through which power can be transferred from the rotor to wheels; and a second power transfer path which is composed of the engine rotation transfer member, the first one-way clutch, and the coupling member, through which power can be transferred from the internal combustion engine to the oil pump, and which intersects the first power transfer path (Pal) at an intersection portion, wherein the intersection portion between the first power transfer path (Pal) and the second power transfer path includes: a carrier disposed on the first power transfer path, one of an outer peripheral side and an inner peripheral side of the carrier being drivably coupled to the rotor and the other being drivably coupled to the wheels; and a pinion member which is disposed on the second power transfer path and which penetrates the carrier in a rotatable state, the pinion member having a gear which is on one side with respect to the first power transfer path (Pal) and which is drivably coupled to the internal combustion engine, and a gear which is on the other side with respect to the first power transfer path (Pal) and which is drivably coupled to the oil pump, and the engagement element, the first one-way clutch, and the second one-way clutch are disposed on one side of the first power transfer path (Pal). an engine rotation transfer member drivably coupled to an internal combustion engine;
