Connector

Abstract

A connector is fitted to a counter connector along a fitting direction and includes a contact pair CP1 consisting of a pair of differential signal contacts adjacent to each other and extending along the fitting direction, a ground layer 15 having conductivity and extending so as to oppose the contact pair CP1, and an insulator retaining the contact pair CP1 and the ground layer 15. The ground layer 15 includes an opening portion 18 disposed at a position opposing the contact pair CP1, and of the opening portion 18, a first width size W1 on a front side in the fitting direction is larger than a second width size W2 on a rear side in the fitting direction, and the second width size W2 is smaller than a width size WP of the contact pair CP1.
