PROBLEM TO BE SOLVED: To prevent early damage of a sealing material arranged at a liquid pressure chamber side of a pulsation absorption plate in a pulsation absorption device using the pulsation absorption plate such as a metal diaphragm. SOLUTION: The sealing material 80, the metal diaphragm 10 and a support member 70 arranged in a mounting hole 98 are supported on a cylindrical inner peripheral wall 99 formed on the mounting hole 98 from an outer peripheral side. According to this, even when the metal diaphragm 10 receiving the liquid pressure is deflected/deformed, a new void for causing biting of the sealing material 80 between the metal diaphragm 10 and a housing 90 does not occur.
