A piercing terminal for a coaxial cable composed of a core conductor wire, an inner insulating layer for covering the core conductor wire, an outer conductor-shielding layer for covering the inner insulating layer, and an outer insulating layer for covering the outer conductor-shielding layer, which can electrically connected with the outer conductor-shielding layer when a pair of piercing blades of the piercing terminal is embedded into the outer insulating layer to penetrate the outer insulating layer. The piercing terminal includes: a pair of strips spaced apart at a distance larger than the outer diameter of the core conductor wire and smaller than that of the inner insulating layer and opposed substantially in parallel; a piercing blade formed in the leading end of each strip; and a pair of curved portions outwardly convex with respect to the pair of strips near to the base portion thereof. The piercing terminal can reduce the difference of the impedance between the core conductor wire and piercing terminal and the impedance between the core conductor wire and outer conductor-shielding when electrically connected with the coaxial cable.
