Electrical connector includes an insulative body, first and second terminals, shielding housing, and adhesive. The insulative body has a tongue piece and a base having first and second positioning grooves. Each of the first terminals has a first positioning part received in the insulative body, a first electrical contact part exposed from the tongue piece, and a first bonding part accommodated in a corresponding one of the first positioning grooves and protruding from the base. Each of the second terminals has a second positioning part received in the base, a second electrical contact part exposed from the tongue piece, and a second bonding part accommodated in a corresponding one of the second positioning grooves and protruding from the base. Adhesive is injected into the first and second positioning grooves to encapsulate the first bonding parts in the first positioning grooves and the second bonding parts in the second positioning grooves.
