The invention relates to an instillation container comprising a container main body (A) made of thermoplastic material, and a cap (B) threadedly fittable on the container main body, wherein a liquid instillation sleeve (6) formed at a front end of the container main body is formed with a bottom-closed conical recess (6b) with a large inner diameter at a front end thereof, a liquid instillation hole (6c) is formable or formed in the bottom of the recess, and the cap (B) is provided with a first raised sealing portion (15) for sealing the recess (6b) of the container main body (A) when the cap is mounted. The object of the invention is to provide an instillation container that has improved sealability between the main body container and the cap in the threadedly fitted state and that can properly set the amount of single instillation at the time of instillation. To realize the object, according t o the invention, an outer periphery of the liquid instillation sleeve (6) is provided with a level-difference portion (8a) with an outer diameter sharply decreasing toward the front end (T) of the container main body (A), and a front end projection (8b) formed forwardly of the level-difference portion (8a) and having an outer diameter that does not substantially decrease or change toward the front end, while the cap (B) is provided with a second raised sealing portion (16) that intimately contacts the front end projection (8b) and level-difference portion (8a) when the cap is mounted.
