<p><P>PROBLEM TO BE SOLVED: To provide a joined body joined by using a joining material which can be substituted for the conventional soldering, and in which the use of lead and tin is abolished, and an environmental load caused by heavy metal contamination is solved. <P>SOLUTION: The joined body is obtained by joining two or more members 52. The joint 50 of the members 52 comprises a metal sintered part with a sintered structure of metal. The metal sintered part is obtained, e.g., by interposing a joining material essentially consisting of composite type metal nanoparticles formed by bonding/covering the surroundings of metal nuclei consisting of metal particles with an organic compound in the joint of the members, performing heating/calcinating in a state where the joining material is held to a prescribed position, and joining the members. <P>COPYRIGHT: (C)2004,JPO</p> |
