PROBLEM TO BE SOLVED: To provide a steam injection mechanism capable of suppressing water accumulation on an object to be processed.SOLUTION: There is provided a steam injection mechanism 3 comprising a common channel 31 through which steam supplied from a steam supply source flows and distribution channels 32 to distribute the steam from the common channel, wherein the steam is injected from steam injection orifices 32d formed in distal ends of the distribution channels 32 to an object (a fibrous nonwoven fabric) to be processed. When the steam injection mechanism 3 is located above the fibrous nonwoven fabric, the lowermost region 31d of the common channel 31 functions as a condensed water collecting region and, when the steam injection mechanism 3 is located under the fibrous nonwoven fabric, the uppermost region 31u of the common channel 31 functions as the condensed water collecting region. |
