Abstract
To provide a manufacturing method for an optical pickup in which a movable member carrying an objective lens is supported by a fixed member through a pair of elastic support member groups, which are each made up of a plurality of parallel elastic support members, so as to be movable in focusing and tracking directions. In a suspension unit forming step, two holding members are formed from a synthetic resin by insert molding at different positions of each elastic support member group in a lengthwise direction of the elastic support members, thereby forming a pair of suspension units. In a connecting step, the pair of suspension units are opposed with an arrangement direction of the elastic support members being substantially the same as the focusing direction, and one holding member of each suspension unit is connected to the movable member and the other holding member to the fixed member.
