Abstract
Embodiments of the present invention provide a component-built-in wiring board capable of preventing a defect, such as a crack, resulting from stress concentration at a corner, when a component is accommodated in a housing portion of a core material with resin filler filled therebetween. The component-built-in wiring board can include a component accommodated in the housing portion of a core material, and a laminate portion in which insulating layers and conductor layers are laminated alternately on the core material. A gap between the housing portion of the core material and the component can be filled with a resin filler. In an inner circumferential portion of the housing portion of the core material a first straight chamfered portion is formed at each corner of a rectangle, and in an outer circumferential portion of the component a second straight chamfered portion is formed at each corner of a rectangle.
