PROBLEM TO BE SOLVED: To provide a terminal crimping structure to an aluminum electric wire in which cracks are not generated in a border region between a crimping part for retaining the aluminum electric wire and a conductive crimping part for the aluminum electric wire. SOLUTION: In the terminal crimping structure to the aluminum electric wire in which a terminal 1 equipped with a conductive crimping barrel 1a for the aluminum electric wire and an insulation barrel 1b for crimping a covered part of the aluminum electric wire is crimped to the aluminum electric wire W, when the direction reverse to a direction in which a terminal crimping crimper 101 moves at crimping the terminal 1 is made to be the height direction of the terminal 1, after crimping the terminal, a part of a conductive crimping barrel 1a for the aluminum wire is formed as a low height conductive crimping part 11 for the aluminum electric wire. The other part of the conductive crimping barrel 1a for the aluminum electric wire is formed as a high height crimping part 12 for retaining the aluminum electric wire, and also formed as a tapered crimping part 13 having an inclined part which connects the conductive crimping part 11 for the aluminum electric wire and the crimping part 12 for retaining the aluminum electric wire in the height direction.
