Abstract:
1. A print circuit substrate being connectable with a second print circuit substrate that has a second connection terminal extending from a second wiring pattern, the print circuit substrate comprising: a base material, a first wiring pattern formed on the base material, the first wiring pattern constituting a predetermined circuit pattern, and a first connection terminal having a tapered shape that narrows toward a distal end thereof throughout its entire length, the first connection terminal being formed on the base material and extending from the first wiring pattern, wherein the first connection terminal is able to oppose the second connection terminal of the second print circuit substrate, a fillet defined by the tapered shape of the first connection terminal is formed as the first connection terminal and the second connection terminal are connected; and a distal portion of the first connection terminal is narrower than a proximal end portion of the second connection terminal, wherein the fillet formation area of the first connection terminal and the second connection terminal is defined by LW/2, where W is a width thereof and L is a length thereof.
