To provide a spindle motor and a disk drive, capable of suppressing contact of a drawing wire conducting to a base drawing hole to a hole edge. This invention relates to a spindle motor 1 comprising: a base part 40 having a base part penetration hole 42 penetrating an upper surface 40A and a lower surface 40B; a coil having a leading line 34 led to the lower surface 40B from the upper surface 40A passing through the base part penetration hole 42; a wiring substrate 50 having a land part 51 to which the leading line 34 is connected; an insulation sheet part 52 that covers at least one part of the base part penetration hole 42 and to which the leading line 34 is connected. A thickness T2 of the insulation sheet part 52 is thicker than a thickness T1 of the land part 51. 种主轴马达以及盘片驱动装置，能抑制穿过底座引出孔的引出线与孔缘接触。主轴马达的底座部(40)包括底座部通孔(42)，该底座部通孔(42)将上表面(40A)与下表面(40B)连通。线圈包括穿过底座部通孔(42)并从上表面(40A)被引出至下表面(40B)的引出线(34)。配线基板(50)包括与引出线(34)连接的焊盘部(51)。主轴马达包括绝缘片材部(52)，该绝缘片材部(52)覆盖底座部通孔(42)的至少部分，并与引出线(34)接触。绝缘片材部(52)的厚度(T2)比焊盘部(51)的厚
