Abstract
Provided is a substrate with a built-in electronic component that can minimize occurrence of functional anomaly, damage, or the like in a filter function section of an elastic wave filter that is caused by a deformation of a hollow cover of the elastic wave filter that is built into the substrate. The substrate with a built-in electronic component includes: an SAW filter built into a substrate, a filter function section of the SAW filter being covered by a hollow cover; and a stress absorbing layer that faces the hollow cover of the SAW filter through an insulating layer in the substrate.
