A bellows accumulator has a bellows (13) serving as a movable separating element between a gas side (11) and a fluid side (21). At the movable bellows end during expansion and contraction in the accumulator housing defining a longitudinal axis (9), a closure body (25) closes off the interior space (33) of the bellows (13) in a fluid-tight manner. At its other bellows end (27), the bellows is immovably fixed to the accumulator housing (1). The immovable bellows end (27) is fixed to an end body (31) fixed to the housing, which end body (31) is in the form of a disk with region (37) projecting axially into the interior (33) of the bellows (13) from the main plane (35) of the disk. At least one fluid passage (41, 43) is formed on the projecting region (37), which fluid passage (41, 43) connects the interior space (33) associated with the fluid side (21) to a fluid connection (17) of the accumulator housing (1).
