Abstract

A terminal structure of coaxial cable includes a substrate, a coaxial cable, and a conductive shield member. The substrate includes a ground potential layer therein and a ground electrode thereon which is electrically connected to the ground potential layer through a via. The coaxial cable includes a conductor core, a dielectric body surrounding the conductor core, an external conductor layer surrounding the dielectric body, and an outer coat layer surrounding the external conductor layer. The dielectric body has a first protrusion portion configured to protrude from an end of the external conductor layer. The conductor core has a second protrusion portion configured to protrude from an end of the dielectric body. The second protrusion portion is electrically connected to the substrate. The conductive shield member covers the first protrusion portion and the second protrusion portion, and is connected to the ground electrode.
