Embodiment approach 1

[0051] refer to Figure 11 to Figure 15 , the FPC and the battery pack module according to Embodiment 1 will be described. Figure 11 It is a plan view (viewed from above) schematically showing a state in which the battery pack module according to Embodiment 1 is mounted on the battery pack. Figure 12 It is a side view schematically showing a state in which the battery pack module according to Embodiment 1 is attached to the battery pack. Figure 13 It is a plan view of the FPC of Embodiment 1. In addition, in Figure 11 as well as Figure 13 In , in order to clarify the structure of the FPC easily, the wiring is shown with a dotted line in a see-through manner. Figure 14 is a schematic cross-sectional view of the FPC of Embodiment 1, and is Figure 13 AA section view in . Figure 15 It is a front view of the battery pack module of Embodiment 1, from the connector side (in Figure 11 as well as Figure 12 The left side in the middle) observe the schematic configurati...
