1. A connector for high-speed transmission, comprising:
an insulator with a slot into which a paddle card substrate is fitted;
a plurality of contacts for signal which are disposed at a wall portion surrounding the slot of the insulator and come into contact with electrodes for signal of the paddle card substrate when the paddle card substrate is fitted into the slot;
a plurality of contacts for ground disposed at a wall portion surrounding the slot, and coming into contact with electrodes for ground of the paddle card substrate when the paddle card substrate is fitted into the slot; and
a conductive resin disposed in the insulator, wherein the conductive resin comprises a protrusion portion facing the contact for ground, and wherein the conductive resin is not electrically connected to the contact for signal and is electrically connected to the contact for ground via the protrusion portion.
