A connector structure enables replacement of an STP cable (10B) and a UTP cable (10A) without a large structural change. UTP connection terminals (21A) connected to respective wires (11) of the UTP cable (10A) are accommodated in accommodating portions (26) of a UTP dielectric (22A) such that insertion areas (53) for male terminals (91) are close to each other in a width direction. STP connection terminals (21B) connected to respective wires (11) of the STP cable (10B) are accommodated in accommodating portions (26) of an STP dielectric (22B) such that insertion areas (53) for male terminals (91) are farther apart in the width direction than in the case of the UTP connection terminals (21A). The UTP connection terminals and the STP connection terminals that are accommodated in the accommodating portions (26) have protrusions (34) that are oriented in the same direction when.
