Abstract
There is provided a wiring board capable of strengthening the bonding between an external terminal and a wiring of an external circuit board. A wiring board includes an insulating substrate having two main surfaces facing each other, side surfaces connecting to the two main surfaces and concave portions concave from the side surfaces and connecting to at least one of the two main surfaces; and external terminals disposed from one of the main surfaces to inner surfaces of the respective concave portions, each of the external terminals having a convex-shaped section disposed on one main surface side along each of the concave portions.
Claims9
A wiring board, comprising:
- an insulating substrate having two main surfaces facing each other, side surfaces perpendicular to and connecting to the two main surfaces, and concave portions that are concave into the side surfaces and that connect to at least one of the two main surfaces;
- and
- external terminals disposed from one of the main surfaces to inner surfaces of the respective concave portions, each of the external terminals comprising a main surface area which is located on the one of the main surfaces and has a convex-shaped section, that is convex out from the one of the main surfaces, disposed along each of the concave portions, an interval between the concave portion and the convex-shaped section disposed along the concave portion at a central portion of the concave portion being narrower than an interval between the concave portion and the convex-shaped section disposed along the concave portion at an edge portion of the concave portion.
