ROLLED COPPER FOIL |
摘要 |
A rolled copper foil composed of crystal particles of copper or a copper alloy, wherein an average particle size of the crystal particles composing the outermost surface is not less than 0.2 µm and not greater than 6 µm; a ratio of the average particle size of the crystal particles composing the outermost surface to a thickness of the rolled copper foil is not less than 1% and not greater than 6%; and an intragranular distortion rate found by the following formula (1) when a cross-section perpendicular to a length direction of the rolled copper foil is analyzed by electron backscatter diffraction (EBSD) is not less than 0.5% and not greater than 10%. Intragranular distortion rate % = A / B x 100
(In the above formula (1), (A) represents the area of a region identified through image analysis to have an orientation difference of not less than 1 degree and not greater than 15 degrees, and (B) represents the area of a region identified through image analysis to have an orientation difference of not less than 0 degrees and not greater than 15 degrees). |
