    Abstract: A method of manufacturing a printed circuit board includes arranging a core layer in which a bending prevention portion of at least two layers that are metal layers having different thermal expansion coefficients is disposed between a plurality of insulating members; forming a circuit pattern so as to have a desired pattern on at least one of the inside of the core layer and an outer face of the core layer; and forming an insulating layer including an opening portion that exposes the circuit pattern on the core layer.

    Abstract: An electronic component embedded substrate includes a core structure including a first insulating body and core wiring layers and having a cavity and a stopper layer. An electronic component is disposed in the cavity. The stopper layer includes a first metal layer embedded in the first insulating body and having a portion of an inner surface exposed from the first insulating body, and a second metal layer disposed below the first metal layer and having at least a portion of an upper surface disposed as a bottom surface of the cavity. The cavity has an inner surface of the first metal layer and an inner surface of the first insulating body as a first wall surface and a second wall surface, respectively, and an inclination of the first wall surface is different from an inclination of the second wall surface.
