Provided is a chemical agent attachment tool set which can reliably discharge appropriate amounts of a chemical agent and which does not have problems related to the decreasing effects of the chemical agent caused by a drop in a volatile component even when the chemical agent used is a volatile chemical agent. The chemical agent attachment tool set is provided with: a chemical agent dispensing apparatus (1) which is equipped with a dispensing tool (20) and a cylinder (10) having a dispensing outlet and a container (4) housing a chemical agent in which a gel-like chemical agent is hermetically-sealed. The dispensing tool (20) is provided with a shaft (21), which is inserted into the cylinder (10), and an operating section (22), which is joined to the shaft. Further, the cylinder (10) is provided with an insertion opening (13) for the container housing the chemical agent and an abutting section (14) which abuts the surface to which the chemical agent attaches. The container (4) housing the chemical agent has an opening which is hermetically-sealed in an openable manner and the tip of the shaft (21) has a hole that is slightly smaller than the periphery of the end wall (43), which is positioned on the opposite side of the opening section.
