Abstract:
1. An electronic component incorporated substrate comprising: a first substrate; a second substrate; a spacer unit that electrically connects the first substrate and the second substrate; an electronic component mounted on the first substrate and arranged between the first substrate and the second substrate; a first encapsulating resin formed between the first substrate and the second substrate to encapsulate the electronic component; and a second encapsulating resin formed on a first surface of the first encapsulating resin to fill a space between the first encapsulating resin and the second substrate, wherein the spacer unit includes a stacked structure of a first solder ball, a metal post, and a second solder ball stacked in a stacking direction of the first substrate and the second substrate, the first encapsulating resin is continuous from a region in which the spacer unit is connected to the first substrate to a region in which the electronic component is mounted on the first substrate, and encapsulates a surface of the electronic component facing toward the second encapsulating resin, and the second substrate includes
