Easily polymerizable substance handling device

An easily polymerizable substance handling device comprising:

• a pipeline through which an easily polymerizable substance containing material can flow;
• a tubular member provided as a protrusion from the pipeline and communicating with inside of the pipeline through an opening part formed at the pipeline;
• and
• a cover part dividing inside of the pipeline from the tubular member,
• wherein the cover part has a curved surface on a side closer to inside of the pipeline and is disposed to block at least part of the opening part and have a gap with respect to a peripheral part of the opening part;
• wherein the cover part has a concave surface on the side closer to inside of the pipeline when viewed from the side closer to inside of the pipeline.
