A dynamic vibration absorber and an optical disk device. The dynamic vibration absorber comprises a base chassis (11) holding a spindle motor (13) rotatingly driving a mass-eccentric disk (unshown), a dynamic vibration absorbing element (14a) connected to the base chassis (11) through first elastic bodies (15a) and (15b), and a dynamic vibration absorbing element (14b) connected to the base chassis (11) through first elastic bodies (15c) to (15e). The base chassis (11) and the dynamic vibration absorbing elements (14a) and (14b) are installed on an approximately same plane.
