Abstract: The liquid container according to the present invention includes: a container main body 1 which stores a liquid; an ultrasonic sensor 2 which is disposed so as to contact an outer side wall of the container main body and so as to emit an ultrasonic wave into the liquid; and a reflecting means 3 which is disposed at an inner bottom portion of the container main body 1 and reflects an ultrasonic wave emitted into the liquid from the ultrasonic sensor 2, towards the liquid surface, wherein the reflecting means 3 is disposed at a position, where a distance the ultrasonic wave travels through the liquid, of the path of the ultrasonic wave from the ultrasonic sensor to a reflecting surface of the reflecting means, is greater than a distance at which an insensitive band of the ultrasonic sensor 2 is obtained. With the liquid container of the present invention, it is possible to measure the liquid level in a short period of time, without being affected by the insensitive band of the ultrasonic sensor, even if the liquid level is low.
