When the pair of housings are fitted and connected, the outer surfaces of the inclined plates facing each other in the inverted state are butted in a surface contact state, so that a pair of terminal fittings having the same structure are in a conductive connection state. A terminal fitting characterized by that.   The inclined plate is a projecting piece whose end in a direction extending at a predetermined inclination angle is a free end, and when the inclined plates of the pair of terminal fittings are abutted with each other, the inclination angle is changed. The terminal fitting according to claim 1, wherein a predetermined contact pressure is secured between the inclined plates that are in surface contact by the deformation.
