<p>A clad material 1A for insulating substrates is provided with a Ni layer 4 made of Ni or a Ni alloy, a Ti layer 6 made of Ti or a Ti alloy and arranged on one side of the Ni layer, and a first Al layer 7 made of Al or an Al alloy and arranged on one side of the Ti layer 6 that is opposite to a side of the Ti layer 6 on which the Ni layer 4 is arranged. The Ni layer 4 and the Ti layer 6 are joined by clad rolling. A Ni—Ti series superelastic alloy layer 5 formed by alloying at least Ni of constituent elements of the Ni layer 4 and at least Ti of constituent elements of the Ti layer 6 is interposed between the Ni layer 4 and the Ti layer 6. The Ti layer 6 and the first Al layer 7 are joined by clad rolling in an adjoining manner.</p> |
