Stator and motor

The present invention provides a stator (1) comprising: an annular core back which is formed of a magnetic body; a plurality of teeth which protrude toward an inner side in the radial direction from the core back; and a slot (5) which is formed between the adjoining teeth. The stator (1) further comprises: a first insulator (6A) which is provided at one end of the stator (1) along the central axis of the core back; a second insulator which is provided at the other end of the stator (1) along the central axis of the core back; a coil wire (7) which is continuously wound around every two of the adjoining teeth; and a conductive connection terminal which is fixed to the first insulator (6A) and holds the coil wire (7). The coil wire (7) includes a crossover wire which extends from one of the two of the adjoining teeth toward the other. A first cavity (61a), into which the connection terminal is inserted, is formed in the first insulator (6A). The crossover wire is disposed in the second insulator.
