摘要： PROBLEM TO BE SOLVED: To provide a solder composition which is lead-free and forms an alloy having a melting point higher than that of the composition by forming the alloy during reflow soldering, and as a result can carry out soldering under almost the same temperature condition even when the soldering is further carried out on an already soldered substrate.
SOLUTION: The soldering composition does not contain lead, but contains a first metal component and a second metal component. The first metal component is Sn-3.5 Ag and the second metal component is Ag. The ratio of the first metal component to the second metal component is determined such that the second metal component can diffuse in the molten first metal component during the reflow soldering, and then can produce the alloy having the melting point higher than that of the composition by alloying.

In addition, only another first internal electrode layer has a protruded section for inside connection exposed on the end face and a resistor connection exposed on the side face. The other first internal electrode layers have protruded sections for inside connection exposed on the end face and the exposed surfaces of a plurality of protruded sections for inside connection are connected to each other through a connecting member provided on the end face. In addition, insulating layers are interposed between the connecting members and external electrodes and the second internal electrode layers are led out to the other end face of the laminate and connected to the other external electrode and the two resistor connections exposed on the side faces are connected to each other through a resistor which is set in a state where the resistor does not come into contact with the external electrodes.
