PROBLEM TO BE SOLVED: To improve joining strength.SOLUTION: A joining member 3 comprises: a body part 3a having a joining surface 3b joined to an electrode member 1 while facing a principal surface of the electrode member 1; and an inclined joining surface 3c provided, at an upper position relative to a joining direction of the joining surface 3b to the electrode member 1 in the body part 3a, in an inclined manner while facing a central portion side of the joining surface 3b. When the joining member 3 as described above is pressed against the electrode member 1 via a joining material 2 containing metal particles 2a, the metal particles 2a are pressed in the vertical direction by the joining surface 3b of the body part 3a. At the same time, the metal particles 2a are pressed toward the central portion side of the joining surface 3b by the inclined joining surface 3c. |
