The invention relates to a spindle motor for use in a disk drive apparatus, the disk drive apparatus, and a method of manufacturing a stator. The spindle motor is provided with a base part and the stator. Three coils of the stator comprise three windings. Three common lines form one or two common wire elements through arrangement of a combination part, the combination part combines at least two commen wires, which are taken as an end of a wire in the three windings, of the three commone lines with each other to form one common wire element. The one or two commone wire elements and the wire elements of the three lead-out wire elements whicha re taken as the other end of the wire in the three windings respectively arraive at the lower side of a base portion via individual base through holes, and the individual base through holes are provided with entire sealing parts between the internal circumference of the base through holes and entrie circumferential extent of the wire elements.
