Abstract:
1. A device including: an electronic component and a lead-free solder containing Zn to mount the electronic component to a substrate; the electronic component comprising an element body, and a terminal electrode disposed on the element body, wherein the terminal electrode has: a first electrode layer formed on an external surface of the element body and formed by baking of a conductive paste; a suppression electrode layer to prevent a migration of Zn atoms contained in the lead-free solder into the element body, the suppression electrode layer formed by Ni plating on the first electrode layer; and a second electrode layer formed by Sn plating or Sn alloy plating on the suppression electrode layer, and wherein a thickness of the first electrode layer is set in a range of 5 μm to 200 μm, and a thickness of the suppression electrode layer is set in a range of greater than 6 μm, and less than 8.
