Provided is an electrically conductive aluminum alloy plate having excellent stress relaxation characteristics and bending workability without compromising electrical conductivity, and a method for manufacturing said plate. The electrically conductive aluminum alloy plate is composed of an aluminum alloy containing 0.3-1.5% of Si and 0.3-1.0% of Mg (percentages given with respect to mass), the balance comprising Al and inevitable impurities. Intermetallic compounds in which the average crystal grain size in the rolling direction of the plate surface is 150 µm or less and the maximum length exceeds 3 µm are present in the plate surface in a concentration of 1500/mm2 or less. |
