Abstract
An electronic component includes hollow vias provided within a resin layer such that first ends thereof extend to solders which connect and secure an embedded electronic component, and second ends thereof are sealed by a sealing-member layer, in order to cause the solders that become molten again to flow into the hollow vias such that the solders that have become molten again are housed in the hollow vias, thereby suppressing and preventing the occurrence of solder splash phenomena.

An electronic-component embedded resin substrate comprising:
- a core substrate provided with a land electrode on a surface thereof;
- an electronic component provided with a terminal electrode, the terminal electrode being connected and secured by solder to the land electrode on the core substrate;
- and
- a resin layer arranged on the core substrate so as to cover the electronic component;
- wherein
- the resin layer includes a hollow via which extends to the solder at a first end thereof;
- and
- the electronic-component embedded resin substrate further includes a sealing member arranged to seal the hollow via at a second end thereof.
