Abstract
A spindle motor includes a rotary unit, a bearing mechanism, a stator, a base member, and a connector connected to a leader line extending from the stator through a communication hole of the base member. The connector includes a pedestal and a metal pin. The leader line is connected to a first pin terminal of the metal pin on a hole-positioning lower surface of a hole-defining portion of the pedestal. An upper surface of the metal pin is separated from the pedestal at a specified separation position between the first pin terminal and a second pin terminal. A connection position of the first pin terminal and the leader line on the hole-positioning lower surface is covered with an adhesive agent. The periphery of a gap between the metal pin and the pedestal over an extent from the first pin terminal to the separation position is sealed by the adhesive agent.
