PROBLEM TO BE SOLVED: To provide a securing member capable of suppressing the adhesion to articles other than a member to be secured.SOLUTION: A securing member according to one embodiment comprises a first strip member, a second strip member, and a third strip member, the first to third strip members being folded and laminated. The first strip member has a strip-shaped first substrate layer and a first adhesive layer provided on a first surface of the first substrate layer. The second strip member has a strip-shaped second substrate layer interposed between the first strip member and the third strip member, and a third adhesive layer provided on a first surface of the second substrate layer. The third strip member has a strip-shaped third substrate layer and a third adhesive layer provided on a first surface of the third substrate layer. At least a part of the first adhesive layer is detachably adhered to a second surface of the second substrate layer. At least a part of the second adhesive layer is detachably adhered to a second surface of the third substrate layer. The second substrate layer has elasticity, allowing that the width of at least a part thereof narrows when a tensile load is applied in one direction.SELECTED DRAWING: Figure 1【課題】被固定部材以外の物品に接着することを抑制できる固定部材を提供する。【解決手段】一実施形態に係る固定部材は、第１帯部材と、第２帯部材と、第３帯部材とを備え、第１～第３帯部材が折りたたまれて積層されてなる。第１帯部材は、帯状の第１基材層と、第１基材層の一方面上に設けられる第１接着層とを有し、第２帯部材は、第１帯部材および第３帯部材の間に位置する帯状の第２基材層と、第２基材層の一方面上に設けられる第３接着層とを有し、第３帯部材は、帯状の第３基材層と、第３基材層の一方面上に設けられる第３接着層とを有する。第１接着層の少なくとも一部は、第２基材層の他方面と着脱可能に接着し、第２接着層の少なくとも一部は、第３基材層の他方面と着脱可能に接着し、第２基材層は、弾性を有しており、一方向に引張荷重を加えたときにその少なくとも一部の幅が狭まる。【選択図】図１
