A conductive connecting member is connected to electric wire with insulating coating by a fusing process so that electric continuity therebetween is ensured. The conductive connecting member includes a connecting section and a groove portion. The connecting section is formed by being bent so as to have an inner surface including a bottom surface and both side surfaces to be bonded to the electric wire. The groove portion is formed in the inner surface of the connecting section. The groove portion has a longitudinal groove extending in a direction of the inner surface intersecting with a longitudinal direction of the electric wire. The groove portion is positioned substantially at a center of the longitudinal direction of the electric wire. The groove portion may further have an inclined groove obliquely extending from the longitudinal groove or a transverse groove extending substantially perpendicular to the longitudinal groove.
