具有通气功能的接合构件及使用了该接合构件的接合结构
摘要：
接合构件（1）具备通气膜（11）、设置在通气膜（11）的第一主面（11a）侧的第一粘结层（21）、设置在通气膜（11）的第二主面（11b）侧的第二粘结层（22）、形成于第一粘结层（21）的开口部（21h）、及形成于第二粘结层（22）或者形成于第二粘结层（22）与通气膜11之间的通气槽（1d）。通气槽（1d）包括：从接合构件（1）的外周缘朝向与开口部（21h）对应的位置延伸的第一部分（D1）；及在与开口部（21h）对应的位置处使通气膜（11）的第二主面（11b）露出的第二部分（D2）。在使用接合构件（1）将外壳（31）固定于支承体（32）时，通气槽（1d）在外壳（31）与支承体（32）之间确保从外壳（31）的外部向外壳（31）的内部的通气路径（1v）。
摘要（英）：

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).
