Handling device and producing system of easy-to-polymerize compound

A device for handling an easily polymerizable compound into which a vapor of the easily polymerizable compound is supplied, comprising:

• a condensation part in which the easily polymerizable compound may be condensed inside the device;
• a spreader for the condensation part that spreads a polymerization inhibitor on the condensation part;
• a polymerization inhibitor supply tube that supplies the polymerization inhibitor to the spreader for the condensation part;
• and
• a support means for supporting the polymerization inhibitor supply tube outside the device so that the spreader for the condensation part is supported at a predetermined position inside the device, wherein
• the polymerization inhibitor supply tube passes through an outer wall of the device,
• the support means is provided between the outer wall of the device and a lower portion of the polymerization inhibitor supply tube, and
• the support means extends away from the outer wall of the device in a substantially upwards direction.
