Provided is a fixing member that makes it possible to reliably join a housing and a display section or a display section protective member of a portable electronic device even when the area that can be used for joining is narrow. The fixing member provided by the present invention is for joining a housing and a display section or a display section protective member of a portable electronic device.Said fixing member comprises a foam substrate and an adhesive layer arranged on at least one surface of the foam substrate. The fixing member comprises a narrow width section having a width of less than 2.0 mm. The relationship between the average width W (mm) of the narrow width section, the 100% modulus M (N/mm2 substrate) of the fixing member, and the thickness Hs (mm) of the foam substrate inthe fixing member satisfies the following formula: 0.4/(M*Hs) <= W.
