PROBLEM TO BE SOLVED: To provide a waveguide tube slot antenna capable of stably exhibiting desired antenna characteristics.SOLUTION: There is provided a waveguide tube slot antenna A which includes a waveguide tube 10 that has a waveguide 2 extending in a tube axis direction and is made from a resin, and a plurality of radiation slots 3 provided on the waveguide tube 10, where the waveguide tube 10 is formed of first and second waveguide formation members 11, 12, each having a cross-section with ends in each portion in an extension direction of the waveguide 2 and defining the waveguide 2 when being coupled with the other side. The waveguide tube slot antenna A has a core bar 20 arranged in the tube axis direction, and the core bar 20 is held by both of first and second waveguide tube formation members 11 and 12.SELECTED DRAWING: Figure 2 【課題】所望のアンテナ特性を安定的に発揮し得る導波管スロットアンテナを提供する。【解決手段】管軸方向に延びた導波路２を有する樹脂製の導波管１０と、導波管１０に設けられた複数の放射スロット３とを備えた導波管スロットアンテナＡであって、導波管１０が、導波路２の延在方向各部における横断面が有端状をなし、相手側と結合されることで導波路２を画成する第１および第２の導波管形成部材１１，１２からなるものにおいて、管軸方向に沿って配置された芯金２０を有し、芯金２０が、第１および第２の導波管形成部材１１，１２の双方に保持されている。【選択図】図２
