Provided is a novel pressure pulsation reducing device of a hydraulic system that reduces a stress generated in a metal diaphragm and is excellent in durability. A plurality of concentric recess portions projecting toward an interior space of a pulsation damping member is formed on one of metal diaphragms, and a plurality of concentric recess portions projecting toward the interior space of the pulsation damping member is formed on the other metal diaphragm likewise. When a predetermined pressure is applied to the metal diaphragms, at least one recess portion of one of the metal diaphragms and at least one recess portion of the other metal diaphragm are in contact with each other.
