In a weak mating force female terminal formed with a base plate portion; a pair of elastic curled portions extending from both side ends of the base plate portion so as to be folded over an inner surface of the base plate portion; and a pair of electric contact portions each extending from a middle end of the elastic curled portion so as to be bent outwardly along the inner surface of the base plate portion at an inner end of the elastic curled portion, in particular each of the elastic curled portions is formed with a primary inclined guide portion extending upwardly and outwardly toward a male terminal insertion opening at an outer end of the elastic curled portion; each of the electric contact portions is formed with a secondary inclined guide portion extending upwardly so as to intersect the primary inclined guide portion of the elastic curled portion at an outer end of the electric contact portion; and a pair of thirdly inclined guide portions each of which is disposed between a base of said primary inclined guide portion and a base of said secondary inclined guide portion and extends upwardly.
