Provided is a crimped terminal wire for an automobile that has anticorrosion properties that are stable in a vehicle environment. A crimped terminal wire for an automobile (1) is configured by crimping, to a terminal of an aluminum wire (2) that is an aluminum conductive wire (23) covered with an insulator, a connection terminal (3) made of a copper-based material and comprising a crimping section (30) that is crimped onto the aluminum wire (2) and an electrical contact section (33) for connecting with another terminal, forming a resin resin-covering section (4) on the aluminum wire (2) and a crimped section (12) of the connection terminal (3), and making the resin covering section (4) cover the entire periphery of the crimped section (12). The resin covering section (4) has as its primary constituent a thermoplastic polyamide resin and is formed from materials for which the combined tensile shear strength of the aluminum is at least 6 N/mm2 as measured in compliance with JIS K6850, the rate of elongation as measured in compliance with ASTM D-1708 is at least 100%, and the water absorption rate as measured in compliance with JIS K7209 is 1.0% or less.
