1. An electronic component-embedded module comprising:
an electronic component having a plurality of pads on its surface; and a multilayer substrate which is a multilayer body formed by stacking up a plurality of resin layers and in which a cavity is formed for containing the electronic component, wherein the plurality of resin layers of the multilayer substrate at least includes
a first resin layer at which a plurality of first pattern conductors and a space, which forms the cavity, are formed, anda second resin layer having at least one second pattern conductor and a plurality of third pattern conductors, the plurality of third pattern conductors being capable of having electrical conduction with either of the plurality of first pattern conductors or the plurality of pads, the second resin layer being placed over the first resin layer, the second pattern conductor is arranged around one or more first pads with a gap provided between the second pattern conductor and the one or more first pads when viewed in plan in a layer stacking direction of the first resin layer and the second resin layer, the one or more first pads being one or more of the plurality of pads, when viewed in plan in the layer stacking direction, a portion of the second resin layer is present between the second pattern conductor and the one or more first pads, when viewed in plan in the layer stacking direction, the second pattern conductor is arranged to surround the one or more first pads in a continuous way or in an interrupted way, and in the multilayer substrate, at least a portion of the second resin layer enters into a recess surrounded by the second pattern conductor arranged to surround the one or more first pads in a continuous way or in an interrupted way. |
