Abstract
A terminal connecting method including: removing a insulation film by a predetermined length from one end of a litz wire; inserting to a pressure fixing part a terminal part of the litz wire; compressing a first portion of the pressure fixing part with a first compression force to cause plastic deformation of an entirety of the pressure fixing part, and to temporarily fix the terminal part of the litz wire to the pressure fixing part; compressing a second portion of the pressure fixing part with a second compression force greater than the first compression force to locally cause plastic deformation of the pressure fixing part and the litz wire, the second portion being a part of the first portion; and pouring molten solder from a front end side of the pressure fixing part to firmly fix the litz wire to the terminal metal fitting.
