STATOR, MOTOR, AND VENTILATION DEVICE

This stator comprises an iron core connected in an annular shape, a winding wound around the iron core, an insulator (3) that insulates between the iron core and the winding, a substrate (6), and a terminal pin (12) by which the winding and the substrate (6) are connected. The substrate (6) is provided with a through-hole through which an iron-core-facing surface (6a) and a rear surface (6b) communicate, the through-hole passing through the substrate (6). In a state in which the terminal pin (12) has passed through the through-hole, the terminal pin (12) is provided with an upper connection part (5a) connected to the winding at a position isolated from the rear surface (6b) in a direction opposite the iron core, and a lower connection part (5b) connected to the substrate (6) independently from the upper connection part (5a) in the vicinity of the through-hole. 定子包括：连接成环状的铁芯；卷绕于铁芯的绕组；将铁芯与绕组之间绝缘的绝缘件(3)；基板(6)；和将绕组与基板(6)连接的接线柱(12)。基板(6)包括：贯通基板(6)而将铁芯相对面(6a)与背面(6b)连通的贯通孔，接线柱(12)包括：在贯通了贯通孔的状态下在从背面(6b)向与铁芯相反的方向分离的位置
