Wiring circuit board and wiring circuit board assembly sheet

A wiring circuit board assembly sheet comprising a plurality of wiring circuit boards,

• the wiring circuit board assembly sheet being provided with a support metal layer,
• the wiring circuit board comprising
• the support metal layer;
• an insulating layer disposed on at least one surface in the thickness direction of the support metal layer;
• and
• a wiring layer disposed on one surface in the thickness direction of the insulating layer,
• wherein in a portion not included in the wiring circuit board,
• a plurality of stripe grooves that extends along a predetermined direction orthogonal to the thickness direction and a plurality of recesses that sinks in the thickness direction of the support metal layer are formed on one surface in the thickness direction and/or the other surface in the thickness direction of the support metal layer, and
• wherein the recesses form a two-dimensional code having a generally rectangular shape in plan view by means of a dot pattern, and are disposed so that one side of the two-dimensional code lies along the stripe grooves.
