An electrical connector includes a first insulative housing (21), a number of first contacts (22) retained in the first insulative housing, and a metallic shell shielding on the first insulative housing. Each first contact comprises a main portion, a contacting section (2211) in front of the base portion, and a soldering section (2201) behind the base portion. Each first contact has a first sub-contact (220) and a second sub-contact (221) stacked with each other. The first sub-contact (220) comprises a first main section (2202) and the soldering section, the second sub-contact (221) comprises a second main section (2210) and the contacting section, the first main section is superimposed on the second main section to form the main portion, and the main portion of the first contact has a larger thickness than the contacting section and the soldering section.
