Provided are: a joining structure which is used in a viscous-liquid discharge device, is capable of improving sealing-attachment-structure following properties of a joining part for joining a liquid feed pipe means and a long flow path member, and is capable of completely inhibiting air infiltration into a joined section; and a viscous-liquid discharge device using said joining structure. The joining structure is used in a viscous-liquid discharge device in which only a plastic container can be exchanged after a discharge operation of the viscous liquid. In the joining structure, a sealing attachment means is provided with a flexible cylindrical insertion part. The flexible cylindrical insertion part is inserted into an inner through hole of the long flow path member from the upper end, and as a result the flexible cylindrical insertion part engages with the long flow path member. |
