The invention provides an optical disc apparatus which restricts an operation sound generated from an objective lens driving portion of an optical pickup and has a reduce sound, in an optical disc apparatus, in particular, an optical disc apparatus installing a microphone for recording an external voice therein. Coils ( 107, 108 ), a magnet ( 109 ) and opposing surfaces of a yoke ( 110 ) are respectively arranged at substantially point symmetrical positions with respect to an optical axis ( 111 ) of an objective lens ( 103 ) in a state in which no electric current is applied, the yoke ( 110 ) and a unit base ( 117 ) are connected via a spring member ( 118 ), and the unit base ( 117 ) is mounted to a casing ( 120 ). In this case, the spring member ( 118 ) is connected at a position ( 121 ) forward apart from the objective lens ( 103 ) with respect to the yoke ( 110 ), and is formed so as to have at least a deformation freedom in a direction of the optical axis of the objective lens ( 103 ). The casing ( 120 ) is made in a closed structure surrounding a space in which the unit base ( 117 ), a lens holder ( 106 ), the yoke ( 110 ) and the magnet ( 109 ) are arranged, except a surface opposing to a disc-like recording medium ( 104 ).
