To be able to further reduce deterioration in signal quality, there is provided a connector including: a signal pin (11) that is connected to a wiring pattern (15) on a mounted substrate (14) and that transmits a signal to an inside and an outside of any apparatus, the mounted substrate (14) having an end disposed in the apparatus; and a shell (13) that is formed of an electric conductor and grounded to ground potential on the mounted substrate (14), in a manner that the shell (13) covers the signal pin (11) in a region in which the signal pin (11) stretches toward the mounted substrate (14).
