Copper strip for edgewise bending, component for electric or electronic device, and bus bar

Abstract

A copper strip for edgewise bending can be edgewise-bent under a condition that a ratio R/W of a bending radius R to a width W is 5.0 or less. In the copper strip, a thickness t is in a range of 1 mm or more and 10 mm or less, and area ratio B/(A+B) is in a range of more than 10% and 100% or less in a square region where the length of one side is 1/10 of the thickness t, where an intersection of a straight line which contacts a surface and is parallel to a width direction and a straight line which contacts an end face and is perpendicular to the width direction is used as a reference in a cross section orthogonal to a longitudinal direction, A is an area where copper is present, and B is an area where copper is not present.
