In an adsorption-type refrigerating apparatus, an adsorber includes therein an adsorbent having a temperature-dependent characteristic in which an amount adsorbed in an adsorption step is larger than an amount adsorbed in a desorption step, even when a vapor pressure rate in the adsorption step is equal to or lower than a vapor pressure rate in the desorption step. Therefore, even when the cooling temperature of outside air for cooling the adsorbent increases, a sufficient cooling capacity can be obtained. In addition, a difference between the amount adsorbed in the adsorption step and the amount adsorbed in the desorption step can be made larger.
