PRINT SUBSTRATE, ELECTRONIC DEVICE, AND METHOD OF MANUFACTURING PRINT SUBSTRATE

摘要

A print substrate includes: a base; a tapered shape hole that is formed in the base, and is configured to have a diameter which continuously changes along a thickness direction of the base; a conductive film that covers a wall surface of the tapered shape hole; a plurality of wirings that are formed in locations which are different from each other in the thickness direction of the base, and that are connected to the conductive film; and a cylindrical shape hole that communicates with the tapered shape hole on a smaller diameter side of the tapered shape hole, and that has a smaller diameter than the diameter of the tapered shape hole in the locations in which the wirings, formed on the smaller diameter side of the tapered shape hole, of the plurality of wirings are connected to the conductive film.
