Abstract:
1. An electronic component contained substrate comprising: a first wiring substrate and a second wiring substrate adjacent and spaced apart from the first wiring substrate such that the first wiring substrate and the second wiring substrate define a space therebetween; an electronic component having a connection terminal on a lower surface which is mounted to a surface of the first wiring substrate facing the space between the first and second wiring substrates; a solder ball disposed in the space between the first and second wiring substrates which electrically connects the first and second wiring substrates; and a sealing resin which seals the space between the first and second wiring substrates such that the electronic component and the solder ball is substantially sealed by the sealing resin, wherein the second wiring substrate, which faces the first wiring substrate on which the electronic component is mounted, has an opening portion, which is larger than a planar shape of the electronic component, in a position that opposes the electronic component, wherein the solder ball has a predetermined size such that an upper portion of the electronic component extends into and is accommodated in the opening portion of the second wiring substrate, and wherein the electronic component is mounted to the surface of the first wiring substrate by flip-chip bonding.
