Abstract:

A joining member (1) comprises: a ventilation film (11); a first adhesive layer (21) which is provided at a first main surface (11a) side of the ventilation film (11); a second adhesive layer (22) which is provided at a second main surface (11b) side of the ventilation film (11); an opening (21h) which is formed in the first adhesive layer (21); and a ventilation groove (1d) which is formed in the second adhesive layer (22) or between the second adhesive layer (22) and the ventilation film (11). The ventilation groove (1d) includes: a first portion (D1) which extends from the outer peripheral edge of the joining member (1) towards a position corresponding to the opening (21h); and a second portion (D2) which exposes the second main surface (11b) of the ventilation film (11), at the position corresponding to the opening (21h). The ventilation groove (1d) ensures that a ventilation path (1v) from the outside of a housing (31) to the inside of the housing (31) is between the housing (31) and a support body (32) when the joining member (1) is used to secure the housing (31) to the support body (32).
