In addition, as described above, the intermediate portion 131 of each contact 130 has a substantially crank shape when viewed along the X direction. Accordingly, in the two signal contacts 130 constituting each contact pair 140, the distance between the second signal contact portions 135 is larger than the distance between the first signal contact portions 133. That is, pitch conversion is performed on the front side and the rear side of the signal contact 130.

Further, when attention is paid to two adjacent contact pairs 140 in the Y direction (that is, the nearest odd-numbered contact pair 140 _O and even-numbered contact pair 140 _E in the Y direction), these two contact pairs 140 are represented by X When a virtual axis extending in the direction is a rotation target axis, when one contact pair 140 (for example, odd-numbered contact pair 140 _O ) is rotated 180 degrees around the rotation target axis, the other contact pair 140 is rotated. The contact pairs 140 are arranged so as to coincide with the contact pairs 140 (for example, even-numbered contact pairs 140 _E ). Accordingly, the first signal contact portions 133 are arranged in a row, while the second signal contact portions 135 are arranged in two rows. That is, the array conversion is performed on the front side and the rear side of the signal contact 130.

  The signal contact 130 and the ground member 150 are incorporated in the housing 110 so as to satisfy the above arrangement condition. Specifically, first, the first signal contact portion 133 is press-fitted into the contact holding portion 115 from the rear of the housing 110, and the second signal contact portion 135 is held in the contact holding portion 120 or the contact holding so as to satisfy the above-described requirements. Press fit into the part 121. At this time, a contact holding portion in which the first signal contact portion 133 is not inserted between the first signal contact portion 133 of one contact pair 140 and the first signal contact portion 133 of the contact pair 140 adjacent thereto. 115 is left. Next, the first ground contact part 153 is press-fitted into the contact holding part 115 in which the first signal contact part 133 is not inserted, and the second ground contact part 155 is press-fitted into the contact holding part 120 or the contact holding part 121. To do. At this time, the fixed portion 159 is press-fitted into the fixing hole 123 of the housing 110 and the shell connecting portion 157 is fitted into the recess 122.
