Abstract
A method of manufacturing a component-embedded substrate includes a resist forming step in which a patterning resist is formed on a support, a patterning step in which a through hole extending through the resist is formed by performing patterning on the resist, a first-electrode forming step in which a through-via electrode is formed by filling the through hole with an electrode material, a resist removing step in which the resist is removed, a component placement step in which an electronic component is placed, a substrate forming step in which a resin substrate is formed by sealing the electronic component with a resin that includes a filler having a diameter larger than the surface roughness of a side surface of the through-via electrode, and a removing step in which the support is removed from the resin substrate. The first-electrode forming step is performed before the substrate forming step is performed.
