1. A terminal unit, comprising:
a male terminal; and
a female terminal,
the male terminal including a columnar connecting portion extending while having a circular cross-section, the columnar connecting portion having a tapered shape gradually reduced in diameter toward a tip side,
the female terminal including a tubular connecting portion to be conductively connected to the columnar connecting portion of the male terminal and having a first peripheral wall portion and a second peripheral wall portion arranged to face each other, and a resilient member for biasing the first and second peripheral wall portions in mutually approaching directions,
the first and second peripheral wall portions being displaceable away from each other against a biasing force of the resilient member,
a facing gap between the first and second peripheral wall portions becoming gradually smaller from a base end side toward a tip side of the tubular connecting portion in an inserting direction of the columnar connecting portion into the tubular connecting portion,
at least one of the first and second peripheral wall portions including a contact point portion located between the base end side and the tip side and projecting radially inward,
a tip part of the columnar connecting portion having an outer diameter to be insertable into the tubular connecting portion without contacting the contact point portion with the columnar connecting portion and the tubular connecting portion concentrically arranged, a press-fit region to be press-fit to the contact point portion being provided on a part of the columnar connecting portion closer to the base end side than the tip part,
the female terminal including a pair of tip side plate portions,
the pair of tip side plate portions projecting radially outwardly of the tubular connecting portion from a pair of mutually facing circumferential end parts of the first and second peripheral wall portions while being separated from each other, the pair of tip side plate portions being deflectable and deformable in mutually approaching directions,
the resilient member biasing the pair of tip side plate portions in the mutually approaching directions, and
at least one of a pair of facing surfaces of the pair of tip side plate portions being provided with a stopper portion projecting toward the other facing surface at a position closer to the tubular connecting portion than tip parts of the tip side plate portions.
