To provide an electrical connector for a flat type conductor that can ensure a good contact state between the flat type conductor and a terminal.SOLUTION: A reinforcing metal fitting 40 includes a plurality of base portions extending along the peripheral edge of a rear end opening 11A on both end sides of a housing 10 in a terminal arrangement direction, and a plurality of guide portions which extend from the plurality of base portions to the inside of a receiving portion 11 and can guide the flat type conductor C on a plate surface along the inner surface of the receiving portion 11. The plurality of base portions each include an upper base portion 41 and a lower base portion 42 which are located on both sides of the rear end opening 11A with the rear end opening 11A sandwiched therebetween, and extend in parallel with each other in the terminal arrangement direction, and a side base portion 43 that is located outside the rear end opening 11A in the terminal arrangement direction and connects the upper base portion 41 and the lower base portion 42. The upper base portion 41, the lower base portion 42, and the side base portion 43 each have a plate surface facing the rear end surface of the housing 10. The plurality of guide portions each include an upper guide portion 44 extending from the upper base portion 41, a lower guide portion 45 extending from the lower base portion 42, and a side guide portion 46 extending from the side base portion 43.SELECTED DRAWING: Figure 1
