A layered structure of wire(s) comprising a wiring layer made of a low resistance metal containing aluminum, copper or silver; and an alloy layer made of an intermediate phase containing the low resistance metal and a refractory metal. The refractory metal is molybdenum. There is also formed a layered structure of wire(s) made of an aluminum alloy containing a lanthanoid, wherein a number average crystal grain size is 16.9 nm or more. Crystal grain size may be larger than a mean free path of electrons to provide a layered structure of wire(s) with a reduced resistance.
