PROBLEM TO BE SOLVED: To provide a cantilever which exhibits bending characteristics equal to or close to those of a cantilever formed using only a spring member while exhibiting excellent electric conductivity. SOLUTION: The cantilever 1 positions the cross section of an inner layer 2 at a position superimposed on the bending neutral axis L of the cantilever 1 or a position in the vicinity of the neutral axis L and laminates the inner layer 2 at a position at which the gravity center axis G of the cross section of the inner layer 2 is shifted from the neutral axis L of the cantilever 1 toward the tensile stress occurrence side. Outer layers 3, 4 are laminated so that they hold the inner layer 2 in between them from both the tensile stress occurrence side and the compression stress occurrence side of the inner layer 2.
