PROBLEM TO BE SOLVED: To provide a joining method by which the thickness of a joint layer including metal nanoparticles is made constant and uniform. SOLUTION: A material 12 to be joined is pressed until the lower surface of the material 12 to be joined is brought into contact with spacers 13. By this pressing step, a paste layer 25 is compressed, and the thickness of the paste layer 25 is made A. Since the spacers 13 are longitudinally and laterally arranged, there is no possibility that the material 12 to be joined is inclined. As a result, a paste layer 25 of which the thickness is constant and uniform is obtained. By using the spacers 13, the thickness of a joint layer including metal nanoparticles is made constant and uniform. COPYRIGHT: (C)2011,JPO&INPIT
