A copper-titanium alloy which exhibits large fluctuations in Ti concentration is provided. A copper-titanium alloy which is for use in an electronic component and which contains 2.0 to 4.0mass% of Ti, and contains, as the third element, 0 to 0.5mass% of at least one element selected from the group consisting of Fe, Co, Mg, Si, Ni, Cr, Zr, Mo, V, Nb, Mn, B and P with the balance being copper and unavoidable impurities, wherein when the area analysis of Ti concentration of a matrix is conducted in regard to the <100> textured crystal grains in a cross section parallel to the rolling direction, the difference between the maximum Ti concentration and the minimum Ti concentration is 5 to 16mass%. |
