This lacrimal duct tube includes: a pair of tube-shaped members which each have, provided to one end thereof, an opening communicating with a lumen, and which each have, provided to a wall section thereof, an aperture for guiding a lacrimal-duct-tube operation tool into the lumen and a connection member which connects other ends of the tube-shaped members to each other. A surface of each of the tube-shaped members includes hydrophilic coating sections, and an uncoated section where the hydrophilic coating is not formed. Engagement parts which engage with tips of the rod-shaped lacrimal-duct-tube operation tools are included in the lumina in the vicinity of the openings. It is preferable that the uncoated sections be formed so as not to overlap the tube-shaped member surfaces in positions where the engagement parts are provided. The lacrimal duct tube can be suitably used for various lacrimal-duct-obstruction treatments. In cases when a sheath is to be employed, like in sheath-guided endoscopic-assisted probing, the lacrimal duct tube can be securely fixed to the sheath while exhibiting excellent sheath insertion properties. Furthermore, in cases when the lacrimal duct tube is to be directly inserted into the lacrimal duct, the lacrimal duct tube exhibits excellent lacrimal-duct passage properties, and excellent operability.Linvention concerne un tube pour voies lacrymales comprenant : une paire déléments en forme de tube qui présentent chacun, en une extrémité correspondante, une ouverture en communication avec une lumière et qui présentent chacun, en une section de paroi correspondante, un orifice pour guider un outil dintervention à tube pour voies lacrymales dans la lumière et un élément de liaison qui relie les autres extrémités des éléments en forme de tube lune à lautre. Une surface de chacun des éléments en forme de tube comprend des sections à revêtement hydrophile et une section non revêtue où le revêtement hydrophile nest pas formé. Des parties de mise en
