Assembly sheet

An assembly sheet comprising:

• a plurality of wiring circuit boards,
• a support portion supporting the plurality of wiring circuit boards,
• a connecting portion connecting the plurality of wiring circuit boards to the support portion, and
• an opening portion disposed between the plurality of wiring circuit boards and the support portion, wherein
• the plurality of wiring circuit boards include
• a first wiring circuit board including a metal support layer, a base insulating layer, and a conductive layer in order toward a thickness direction, and
• a second wiring circuit board including a metal support layer, a base insulating layer, and a conductive layer in order toward the thickness direction and disposed spaced from the first wiring circuit board;
• the support portion includes a first support portion supporting the first wiring circuit board and the second wiring circuit board from one side in a first direction perpendicular to an alignment direction in which the first wiring circuit board and the second wiring circuit board are aligned and the thickness direction;
• the connecting portion includes
• a first connecting portion connecting the first wiring circuit board to the support portion and crossing the opening portion and
• a second connecting portion connecting the second wiring circuit board to the support portion and crossing the opening portion;
• the support portion is not disposed between the first wiring circuit board and the second wiring circuit board;
• the connecting portion is not disposed between the first wiring circuit board and the second wiring circuit board;
• the first wiring circuit board includes
• a first main body portion connected to the first connecting portion, and
• a first protrusion portion protruding from an end edge of the first main body portion toward the support portion;
• the second wiring circuit board includes
• a second main body portion connected to the second connecting portion and having the same shape as the first main body portion;
• and
• a first line passing a center of the first main body portion along the alignment direction and a second line passing the center of the second main body portion along the alignment direction are deviated so that a protrusion amount of the first protrusion portion with respect to one end edge of the second main body portion in the first direction is small.
