  The first sub connection support portion 41 is positioned on one side in the lateral direction with respect to the suspension board with circuit 2 positioned at one end in the lateral direction among the plurality of suspension boards with circuit 2. The first sub connection support portion 41 connects the outrigger 51 included in the suspension board with circuit 2 located at one end in the lateral direction to the frame 3.

  The outrigger 51 connected to the first sub connection support portion 41 is the outrigger 51 located on one side in the lateral direction of the pair of outriggers 51 provided in the suspension board with circuit 2 located at one end in the lateral direction.

  The first sub connection support portion 41 has the same configuration as the outrigger connection support portion 45 except that the first branch portion 47B and the second connection support portion 48 are not provided.

  The second sub connection support portion 42 is located on the other side in the lateral direction with respect to the suspension board with circuit 2 located at the other end in the lateral direction among the plurality of suspension boards with circuit 2. The second sub connection support portion 42 connects the outrigger 51 included in the suspension board with circuit 2 located at the other end in the lateral direction to the frame 3.

  The outrigger 51 connected to the second sub connection support portion 42 is the outrigger 51 located on the other side in the lateral direction of the pair of outriggers 51 provided in the suspension board with circuit 2 located at the other end in the lateral direction.

  The second sub connection support 42 has the same configuration as the outrigger connection support 45 except that the second branch 47 C and the third connection support 49 are not provided.

  In the second embodiment, the suspension boards 2 with circuits are separated from the frame 3 by cutting the main body connecting portion 9 and cutting the second connection support portion 48 and the third connection support portion 49. Can.

  In the second embodiment, the outrigger connecting and supporting unit 45 connects the outrigger 51 and the frame 3 provided in one of the suspension boards with circuit 2 adjacent to each other, and the other suspension board with circuit The outrigger 51 and the frame 3 provided in 2 are connected.

  Therefore, the outrigger 51 (one outrigger 510) provided in one of the suspension boards with circuit 2 and the outrigger 51 (the other outrigger 511) included in the other suspension board 2 with circuit are collectively provided by the outrigger connecting support 45. It can be reinforced. As a result, the number of outrigger connection support portions 45 can be reduced, and the configuration of the assembly sheet 1 can be simplified.

  Further, in the outrigger connection support portion 45, the first connection support portion 47 is shared, and the second connection support portion 48 and the third connection support portion 49 support one outrigger 510 and the other outrigger 511, respectively. can do. Therefore, the simplification of the further structure of the assembly sheet 1 can be achieved.

  Also according to such a second embodiment, the same operation and effect as those of the above-described first embodiment can be achieved. In addition, the first embodiment, the second embodiment and the modification can be combined as appropriate.
