Patent ID: 7566584

Claim:
A manufacturing method of an electronic substrate, the method comprising: embedding electronic components in a first surface of a resin substrate, the electronic components being discrete components, the first surface being in a semi-cured state, the semi-cured state being a state prior to providing energy to a resin which cures upon the provision of energy, by heating or by irradiation with UV or other light; forming an insulating layer on the first surface, in which the electronic components have been embedded, of the resin substrate, the insulating layer covering the electronic components and the first surface, at least a part of external connection electrodes of the electronic components being exposed from the insulating layer; and forming a wiring pattern connected to at least the external connection electrodes of the electronic components, the forming of the wiring pattern comprising disposing first liquid droplets containing conductive material on the first surface of the resin substrate on which the insulating layer has been formed, wherein the embedding of the electronic components comprises: heating the electronic components to a temperature lower than a curing temperature of the resin substrate; bringing the heated electronic components into contact with a plurality of places on the resin substrate and causing the places of the resin substrate to be selectively softened; and pressing the electronic components into the softened places on the resin substrate.
