To provide an adsorbent refrigerator for improving the heating or cooling efficiency of a refrigerant and an adsorbent by improving thermal contact performance, reducing manufacturing manhours, and reducing a manufacturing cost by smoothing a flow of the refrigerant between a heat transfer pipe and the adsorbent, and reducing thermal contact resistance between the heat transfer pipe side and the adsorbent side.

This adsorption type refrigerator constitutes the heat transfer pipe by fixing a plate-like fin in the shaft direction of a pipe body on the outer peripheral surface of the pipe body by frictional pressure contact, and is characterized by constituting an adsorbent heat exchanger by arranging a plurality of heat transfer pipes in a row, and juxtaposing a plurality of adsorption elements loaded with the adsorbents between the heat transfer pipes.
