An evaluation method for evaluating a vehicle-charging connector in coolability by connecting an evaluation jig to the charging connector, the charging connector including a pair of male terminals coolable with a coolant, the evaluation jig including a pair of female terminals connectable to the pair of male terminals, the pair of female terminals being connected to the pair of male terminals in evaluating the charging connector in coolability, the method comprising: connecting the pair of female terminals to the pair of male terminals; adjusting a contact resistance between the male terminal and the female terminal such that contact resistance between the male terminal and the female terminal is 0.06 mΩ or more and 0.15 mΩ or less; and after the adjusting the contact resistance, evaluating the coolability depending on whether the male terminal and the female terminal have a temperature of 90°C or lower when a charging current of 400 A is supplied to the male terminal and the female terminal for 30 minutes, wherein the female terminal used in the step of connecting includes a plurality of contact pieces which are each configured to contact the male terminal and which are spaced about a center axis, the plurality of contact pieces each having a flexible piece having a shape extending in a direction parallel to the center axis, and a contact portion protruding toward the center axis from an inner surface of the flexible piece, and in the step of adjusting, the contact resistance between the male terminal and the female terminal is adjusted by an adjustment member that is configured to be attached around the plurality of contact pieces and to apply an external force to the plurality of contact pieces to reduce a diameter of the plurality of contact pieces. connecting the pair of female terminals to the pair of male terminals; adjusting a contact resistance between the male terminal and the female terminal such that contact resistance between the male terminal and the female terminal is 0.06 mΩ or more and 0.15 mΩ or less; and after the adjusting the contact resistance, evaluating the coolability depending on whether the male terminal and the female terminal have a temperature of 90°C or lower when a charging current of 400 A is supplied to the male terminal and the female terminal for 30 minutes, wherein the female terminal used in the step of connecting includes a plurality of contact pieces which are each configured to contact the male terminal and which are spaced about a center axis, the plurality of contact pieces each having a flexible piece having a shape extending in a direction parallel to the center axis, and a contact portion protruding toward the center axis from an inner surface of the flexible piece, and a flexible piece having a shape extending in a direction parallel to the center axis, and a contact portion protruding toward the center axis from an inner surface of the flexible piece, and in the step of adjusting, the contact resistance between the male terminal and the female terminal is adjusted by an adjustment member that is configured to be attached around the plurality of contact pieces and to apply an external force to the plurality of contact pieces to reduce a diameter of the plurality of contact pieces.
