Abstract: A plate-like electric conductor for a busbar having excellent electric conductivity, strength and bendability, and a busbar formed therefrom.The electric conductor formed from an aluminum alloy plate having a thickness of 0.5-12 mm is obtained by subjecting an aluminum alloy consisting essentially of Fe: 0.05-2.0%; Si: 0.05-0.6%; Cu: 0.01-0.35%; by mass, and the balance comprising Al and inevitable impurities to a hot rolling process. The electric conductor has the electric conductivity of 55-60% IACS, tensile strength not lower than 170 MPa and yield strength not lower than 155 MPa, in the as-rolled state at the room temperature, and does not suffer from cracking upon bending by 90° with an inner bending radius equal to its thickness, while having the electric conductivity of 55-60% IACS, tensile strength not lower than 160 MPa, and yield strength not lower than 145 MPa, after a heat treatment at 140-160° C. for not longer than 1,000 hours.
