Abstract: A terminal connecting method includes setting a conductor having a plurality of strands on an upper surface of a bottom portion of an electric wire crimping part of a terminal, caulking the conductor in a manner to cover the conductor, thereby crimping the conductor by a caulking portion extended from the bottom portion, and welding the plurality of strands together in a strands exposed portion of the conductor exposed from tip end edges of the caulking portion by friction between the plurality of strands and a friction tool, after caulking and crimping.
