<P>PROBLEM TO BE SOLVED: To provide a package which has a large current capacity, suppresses occurrence of cracks due to decrease in stress generated, and has high reliability. <P>SOLUTION: There is provided a package comprising: a package outer wall 16; a through hole penetrating through the package outer wall 16; a convex feedthrough 25 fit in the through hole; and a terminal electrode 21b fixed to the convex feedthrough 25. The terminal electrode 21b includes a first metal layer 90, which has a relatively low coefficient of linear thermal expansion and a relatively high resistivity, and second metal layers 80a, 80b which has a relatively high coefficient of linear thermal expansion and a relatively low resistivity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
