CAPACITOR EMBEDDED SUBSTRATE

Abstract: a capacitor embedded substrate that includes: a core substrate that includes a base that defines an opening in a thickness direction; a capacitor component in the opening of the core substrate; and a sealing member sealing the core substrate and the capacitor component, wherein the capacitor component includes a capacitor main body, a through conductor in a through-hole penetrating the capacitor main body in the thickness direction, and a conductor wiring layer on opposed end portions of the through conductor in the thickness direction, a first surface of the core substrate and a first surface of the capacitor component exist on a same plane, and a diameter of an end portion of the through-hole on a first sealing portion side is larger than a diameter of an end portion of the through-hole on a second sealing portion side.
