Summary:In this layered bonding material 10, the coefficient of thermal expansion of a substrate 11 is 5.5-15.5 ppm/K, and a first surface and a second surface are coated with lead-free solder 12a, 12b. Dans ce matériau de liaison en couches 10, le coefficient de dilatation thermique d'un substrat 11 vaut de 5,5 à 15,5 ppm/K, et une première surface et une seconde surface sont revêtues de brasure sans plomb 12a, 12b. 積層接合材料10は、基材11の線膨張係数が5.5~15.5ppm/Kであり、第1面および第2面が鉛フリーはんだ12a、12bでコーティングされている。
