    摘要: In an optical pickup, it is configured such that a first and a second thrust bearings of a motor rotation shaft, a lens holder to be moved in a thrust direction by the motor rotation shaft, and a preload unit which exerts preload of the thrust direction on the lens holder are included, and the second thrust bearing can adjust a position in the thrust direction. In addition, the first and second thrust bearings and the motor rotation shaft are made of conductor, and the optical pickup is manufactured by including the processes of: moving the second thrust bearing in a direction approaching to the motor rotation shaft till electrical continuity between the first thrust bearing and the second thrust bearing is obtained using an electrical continuity checker; subsequently moving the second thrust bearing in a direction departing from the motor rotation shaft; and subsequently fixing the second thrust bearing to the base.
