A conductive wire connection structure of rail-type electrical terminal is able to reduce the yield of waste material in manufacturing, enhance heat dissipation effect and increase operational and motional stability in condition of structural simplification. The conductive wire connection structure includes a conductive support (10) mounted in an insulation case (30). The conductive support (10) is divided into two parts of a U-shaped support main body (40) and a C-shaped wi re connector (50). The wire connector (50) is assembled with a metal leaf spring (20) and disposed on the support main body (40) together with the metal leaf spring (20) for pivotally connecting with the grounding conductive wire coming from a machine or an apparatus. The wire connector (50) and the metal leaf spring (20) are respectively formed with insertion sections (523, 534, 26) for assembling the wire connector (50) with the metal leaf spring (20) to help the support main body (40) to hold the metal leaf spring (20) and prevent the
