Abstract: A shock absorber according to one embodiment includes a damper case provided to hold an outer tube and an inner tube such that an upper end of the outer tube is positioned closer to a side on which a piston rod is disposed than an upper end of the inner tube. The damper case includes a damper housing portion that houses a damper unit, a compression-side communication path through which an inner side of the inner tube and the damper housing portion communicate with each other, an extension-side communication path through which an annular passage and the damper housing portion communicate with each other, and a passage opening which is formed on the opposite side to the piston rod of the outer tube. The extension-side communication path and the annular passage communicate with each other through the passage opening.
