To provide a component forming a breathing tube at low production cost allowing observation of dew condensation or liquid accumulation inside the breathing tube.SOLUTION: A component comprises a tubular body 2 having a foamed wall 3. The foamed wall is corrugated, or of a corrugate profile, where the corrugation profile may comprise alternating outer crests 4 (or annular protrusions) and inner troughs 5 (or annular recesses). The foamed wall is formed from extrusion of a single extrudate. The foamed wall has a sufficient minimum optical transparency to enable, in use, visual detection of liquid (or a condensate that may have formed) within the tubular body.SELECTED DRAWING: Figure 1 【課題】呼吸管内の結露または液体の蓄積を観察可能な、製造コストの低い呼吸管を形成する構成要素を提供する。【解決手段】発泡壁３を有する管状本体２を含み、発泡壁は波形であるか波形の外形のものとされ、波形の外形は交互する外部波頂部４（または環状突出部）と内部波底部５（または環状凹部）とを含み得る。発泡壁は単一押出成形物の押し出しにより形成される。発泡壁は、使用時、管状本体内の液体（または形成されている可能性のある凝縮物）の視覚的検出を可能にするよう十分な最低限の光透過性を有するものである。【選択図】図１
