The disclosure is a battery temperature raising device for hybrid vehicle that raises the temperature of a battery. In an engine travelling mode, when an engine water temperature is higher than a specified cooling water temperature, a first battery circuit is connected to a main circuit and the temperature of the battery is raised by cooling water in the main circuit (first temperature raising control). In a motor travelling mode, when a motor generator temperature is higher than a battery temperature, the first battery circuit and a heat exchanger flow path are connected to the main circuit, and thereby a closed circuit through which cooling water circulates without passing through an engine is formed, and the temperature of the battery is raised by the cooling water that is raised in temperature by heat exchange with a refrigerant in a heat exchanger (second temperature raising control).
