Claim:
1. An electronic device comprising a semiconductor substrate having a plurality of vertical conductors, each of the vertical conductors provided with an insulating material-filled layer in a vertical hole, the semiconductor substrate having the vertical hole extending in a thickness direction thereof, the insulating material-filled layer being a ring-shaped layer filled in the vertical hole for covering an inner periphery thereof, and the insulating material-filled layer substantially made from a liquid glass and a nanocomposite ceramic, the liquid glass containing at least one of Na the nanocomposite ceramic having a specific resistance of greater than 10 the vertical conductors being a solidified metal body filled in an area surrounded by the insulating material-filled layer, wherein the vertical conductors are aligned with each other at a pitch of 4 to 100 μm, wherein each of the vertical conductors is surrounded by the insulating material-filled layer inside the vertical hole, wherein the nanocomposite ceramic has a nanocomposite structure selected from the group consisting of: a structure where nanoparticles are dispersed in crystal grains of an element; or a structure where nanoparticles are dispersed in grain boundaries.
