Male terminal with curved interconnecting portion

A male terminal, comprising:

• a wire connection portion to which an electric wire is connectable;
• a male-type electrical contact portion, to which a mating female terminal is electrically connectable, including a bottom plate portion, the electrical contact portion being formed by bending one free side edge portion of the bottom plate portion thereof;
• a box-like portion provided between the wire connection portion and the electrical contact portion;
• and
• an interconnecting portion interconnecting the box-like portion and the electrical contact portion, the interconnecting portion including:
• an upper wall surface portion extending from the one free side edge portion to the box-like portion,
• a side wall surface portion bent outwardly from the upper wall surface portion, and
• a bottom wall surface portion extending from the bottom plate portion of the electrical contact portion to the box-like portion,
• wherein the upper wall surface portion of the interconnecting portion is bent toward the bottom wall surface portion of the interconnecting portion and extends in a peripheral direction of the interconnecting portion,
• wherein an area of intersection of the upper wall surface portion and the electrical contact portion is defined by a curved surface, and
• wherein said area of intersection has a hollow lateral cross section.
