Abstract: An assembly sheet includes a supporting portion, a plurality of wiring circuit boards, and a joint portion. The supporting portion supports the plurality of wiring circuit boards. The supporting portion surrounds the plurality of wiring circuit boards while being separated from the plurality of wiring circuit boards by an interval. The joint portion joins the plurality of wiring circuit boards to the supporting portion. The plurality of wiring circuit boards includes a first wiring circuit board and a second wiring circuit board. The second wiring circuit board is arranged next to the first wiring circuit board while being separated from the first wiring circuit board by an interval. The second wiring circuit board is symmetrical to the first wiring circuit board with respect to a point centered therebetween. The supporting portion includes a first and second mark. The second mark is asymmetrical to the first with respect to the point.

Abstract: Provided is a wiring circuit board and a wiring circuit board assembly that allow suppression of the recognition error of the dot pattern. The wiring circuit board includes a metal supporting layer, an insulating base layer, and a wiring layer. The wiring circuit board further includes a plurality of streak groove portions disposed on one surface of the metal supporting layer in the thickness direction and a plurality of concave portions depressed in the metal supporting layer in the thickness direction. The plurality of concave portions forms a dot pattern. Each of the dots in dot pattern has one concave surface. The concave surface has an approximately spherical cap shape or an approximately cone shape.
