Abstract: When a second junction portion of a terminal is pressed in the opposite direction of the direction of contact with a mating terminal, a first junction portion attempts to be displaced relatively in the direction of contact with the mating terminal as compared to the second junction portion while in a of state contact with the mating terminal, and accordingly, contact pressure of the first junction portion as to the mating terminal increases. Thus, after the mating terminal comes into contact with the first junction portion, contact pressure of the first junction portion as to the mating terminal is not reduced even when the mating terminal comes into contact with the second junction portion.
