摘要: 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.
