<p>Provided by the present invention is a laminated structure with good use efficiency, in which diffusion of tin from an indium-tin solder material to an indium target is favorably suppressed, and a method for producing the same. The laminated structure has a backing plate, an indium-tin solder material, and an indium target laminated in this order, and the concentration of tin in the 2.5 to 3.0 mm thickness range of the indium target from the indium-tin solder material side surface is 5 wtppm or less.</p> |
