Abstract: A conductor crimping part is crimped onto a terminal metal fitting onto a conductor exposed at a terminal part of an electric wire. A crimped part of the conductor is intimately contacted with a rubber cap seal in such a way as not to be exposed to the outside. Thus, the conductor of the crimped part is sealed in such a manner as to prevent insulation performance from being degraded by infiltration of water contents and oil contents into a connecting part and permeation of the water contents and the oil contents among the wires, which respectively include the conductors.
