PROBLEM TO BE SOLVED: To provide a valve timing adjuster capable of realizing adjustment to a valve timing suitable for an internal combustion engine and the suppression of hammering noise. SOLUTION: This valve timing adjuster comprises: a housing 18 as a first rotating body rotated together with a drive shaft; a vane rotor 14 as a second rotating body rotated together with a driven shaft 2, forming advancing chambers 51-54 and retarding chambers 55-58 in the rotating direction between itself and the housing 18, and driving the driven shaft 2 to the advancing side or the retarding side relative to the drive shaft by supplying a hydraulic oil into the advancing chambers 51-54 or the retarding chambers 55-58; and a control part 30 as a supply control means alternately repeating an advancing angle supply period for supplying the hydraulic oil into the advancing chambers 51-54 and a retarding supply period for supplying the hydraulic oil into the retarding chambers 55-58 when the phase of the driven shaft 2 relative to the drive shaft is limited to a target phase range.
