An in-vehicle absorption heat pump device comprises a regenerator; an in-vehicle heat source heating absorbent in the regenerator; a gas-liquid separator; a condenser condensing gas phase separated from the absorbent; an evaporator evaporating a condensate to form vapor; an absorber for bringing the relatively concentrated absorbent in liquid phase in contact with the gas phase to cause the absorbent to absorb the gas phase and be relatively diluted; an absorbent circulation source circulating the absorbent; a bypass passage connecting a liquid-phase storing portion of the gas-liquid separator and the regenerator while bypassing the absorber; and a bypass transfer source in the bypass passage returning the absorbent in the gas-liquid separator to the regenerator. To dilute absorbent in the absorber, a diluent passage allows the condenser and the absorber to communicate and the condensate in the condenser to be supplied to the absorber through the diluent passage by a dilution element.
