PROBLEM TO BE SOLVED: To provide an adsorption heat pump high in the difference between moisture adsorption amounts in adsorption and desorption in an adsorbent material, allowing regeneration (desorption) of the adsorbent material at a low temperature, and allowing efficient driving using a heat source of a low temperature. SOLUTION: In this adsorption heat pump provided with (a) an adsorptive, (b) an adsorption and desorption part provided with the adsorbent material for absorbing and desorbing the adsorptive, (c) an evaporation part connected to the adsorption and desorption part to evaporate the adsorptive, and (d) a condenser part connected to the adsorption and desorption part to condense the adsorptive, (1) the adsorptive contains zeolite containing aluminum and phosphorous in its skeletal structure, (2) the adsorbent material is an aqueous-vapor- pressure adsorbing material having a range of which the moisture adsorption amount difference in the adsorbing material found by an expression: the moisture adsorption amount difference=Q2-Q1 (where Q1 is the adsorption amount in relative aqueous vapor pressureϕ1 found based on an aqueous vapor desorption isothermal line measured at a desorption temperature T3 in the adsorption and desorption part, and Q2 is the adsorption amount in relative aqueous vapor pressureϕ2 found based on an aqueous vapor adsorption isothermal line measured at an adsorption temperature T4 in the adsorption and desorption part) is 0.15 g/g or more, in an area where the relative aqueous vapor pressureϕ2 of the adsorption and desorption part in an adsorption operation is within a range from 0.115 up to 0.18, and where the relative aqueous vapor pressureϕ1 of the adsorption and desorption part in an desorption operation is within a range from 0.1 up to 0.14.
