ABSTRACT:
A prism of an ink tank has a function for reflecting light, which is incident from the outside, to the outside when no liquid is present in a liquid chamber and not reflecting the light, which is incident from the outside, to the outside when a liquid is present in the liquid chamber, and when the optical characteristics of a material constituting the liquid accommodation container are measured based on a standard according to JIS K7105, the material has optical characteristics equivalent to such optical characteristics that a transmittance of all light beams is 80% or more and a Haze value is equal to or more than 75% and equal to or less than 85%. With the above arrangement, there can be provided an ink tank, which can be operated stably and detect a remaining amount of ink, at a low price.
