PROBLEM TO BE SOLVED: To provide a crimping method and a crimping structure of a crimping terminal against an aluminum electric wire for promoting agglutination characteristics with a conductor by crimping, and of achieving improvement of electric connection performance. SOLUTION: In the case out of a recess forming face 32a of the upper mold 32 to caulk a pair of conductor caulking pieces 14 of a conductor crimping part 4, a dimension of an inner face width of a part to specify the maximum outside face width of the conductor crimping part 4 after caulking is made CCW, the dimension of a diameter of a conductor 101 of the aluminum electric wire 100 is made A, and the dimension of a thickness of the conductor caulking pieces 14 is made t, by caulking the conductor caulking pieces 14 while satisfying a relational equation of "5t≤CCW≤A+2t", the conductor 101 in the conductor crimping part 4 is extended in the longitudinal direction at the larger rate than that of the deformation of the direction orthogonal to the longitudinal direction while suppressing deformation of a direction orthogonal to the longitudinal direction.
