Fusion sheet and wiring member

A fusion sheet, comprising:

• a base material layer including a first surface and a second surface, and
• the base material layer includes two straight regions each extending in a direction different from each other and a connection region connecting the two straight regions;
• a fusion base part partially stacked to the first surface of the base material layer and fusible to a wire-shape transmission member;
• an adhesive base part partially stacked to the second surface of the base material layer and having larger adhesive strength with an adhesive member than the base material layer, wherein
• a plurality of first sections and a plurality of second sections are provided along an extension direction of the base material layer,
• each of the first sections is a section where the fusion base part is stacked to the base material layer other than a laminated section where the adhesive base part is stacked, and
• each of the second sections is a section where the adhesive base part is stacked to the base material layer other than a laminated section where the fusion base part is stacked;
• and
• wherein one of the plurality of first sections is provided in an end portion of one of the two straight regions on one side of the connection region and another of the plurality of first sections is provided in an end portion of the other of the two straight regions on another side of the connection region, and
• one of the plurality of second sections is provided to the connection region.
