A stator of an electric motor includes coil cores, bobbins and coils. The coil cores include six coil cores, which are arranged at equal angular intervals in a circumferential direction. The bobbins respectively cover outer peripheral surfaces of the coil cores, and the coils are respectively wound around outer peripheral surfaces of the bobbins. Among the six coils, each diametrically opposed two coils are electrically connected to each other through the corresponding connection line. Positioning members displace positions of the connection lines from one another, so that interference between the connection lines and interference between the connection line and the coils are limited.
