Abstract
A through-hole via penetrating, in a thickness direction, through a circuit board provided with multiple wiring layers in which a conductor pattern is formed on a surface of an insulating layer, wherein the through-hole via has a first through-hole conductor that is disposed inside a hole penetrating through the circuit board and that is formed from a conductor; a second through-hole conductor that is disposed inside the hole so as to be spaced, in a circumferential direction of the hole, from the first through-hole conductor; a first land portion that connects the first through-hole conductor to the conductor pattern on one insulating layer; and a second land portion that connects the first through-hole conductor with the second through-hole conductor on another insulating layer different from the one insulating layer.
