摘要： Concave serrations are provided in an inner surface of a conductor crimping portion of a crimp terminal. A number of circular concave portions are provided in the inner surface of the conductor crimping portion as the concave serrations so as to be scattered in a state of being spaced aside from one another. A diameter of an inner bottom surface of each circular concave portion is set within a range of 0.15 (an error range is ±0.04) mm to 0.8 (the error range is ±0.04) mm. A serration angle between an extension surface of the inner bottom surface and an inner side surface of each circular concave portion is set within a range of 60 to 90 degrees. A shortest distance of a flat surface portion between peripheries of mutually adjacent circular concave portions is set to be 0.17 (the error range is ±0.09) mm.

摘要： A deterioration degree diagnosis device includes a measurement unit and a diagnosis unit. The measurement unit measures an impedance related to a contact resistance of an electrical connection portion by measuring an AC voltage between metal members and an AC current flowing between the metal members in a state where an AC signal of a predetermined frequency is applied to an electric circuit that connects two metal members in contact via the electrical connection portion. The diagnosis unit diagnoses a deterioration degree of the electrical connection portion based on a reactance component value in the impedance measured by the measurement unit.
