Abstract:
1. A component-incorporated wiring substrate in which a plate-like component is incorporated, comprising: a component including a terminal electrode formed at an end with respect to a first direction, the terminal electrode having, as viewed in plane, a side surface and a main surface; an insulation layer and a conductor layer disposed in alternating layers on a side of the component corresponding to the main surface; and a first via conductor formed in the insulation layer disposed on the side of the component corresponding to the main surface , the first via conductor being connected to the side surface and the main surface of the terminal electrode; wherein the first via conductor is tapered such that the closer to the terminal electrode along a direction of lamination the smaller the via diameter of the first via conductor, the via diameter of the first via conductor as measured in the first direction at a position where the first via conductor is connected to the main surface is greater than a length of the main surface of the terminal electrode as measured in the first direction the terminal electrode includes a first main surface and a second main surface which faces the first main surface in the direction of lamination, the insulation layer and the conductor layer are disposed in alternating layers on a side of the component corresponding to the first main surface and on a side of the component corresponding to the second main surface, and the first via conductor formed in the insulation layer disposed on the side of the component corresponding to the first main surface and the first via conductor formed in the insulation layer disposed on the side of the component corresponding to the second main surface are disposed symmetrically with respect to each other along the direction of lamination.
