PROBLEM TO BE SOLVED: To provide a liquid container and a residual liquid quantity detection device capable of accurately performing appropriate detection according to a residual quantity of ink.SOLUTION: A displacement member 11 is provided which is displaced in a storage part 2 and a detection chamber 5 communicated with the storage part 2 according to a liquid quantity stored in the storage part 2. The displacement member 11 includes a light blocking part 13 that moves between a position where the light of an optical sensor 23 is blocked and a position where it is not blocked according to the displacement, and a regulation member 102 for regulating the movement in a direction different from the direction of the displacement. The inner wall of the detection chamber 5 includes a first area 105 opposed to the light blocking part 13, and a second area 104 opposed to the regulation member 102, and the first area 105 and the second area 104 are connected to each other through an edge line 106 having a face-to-face angle of more than 180 degrees.SELECTED DRAWING: Figure 6 【課題】インクの残量に応じた適切な検出を高精度に行うことが可能な液体容器および液体残量検出装置を提供する。【解決手段】貯留部２に貯留されている液体の量に応じて貯留部２およびこれに連通する検知室５の中で変位する変位部材１１を設ける。この変位部材１１は、変位に応じて光学センサ２３の光を遮光する位置と遮光しない位置との間を移動する遮光部１３と、変位の方向とは異なる方向への移動を規制するための規制部材１０２とを有する。一方、検知室５の内壁は、遮光部１３と対向する第１の領域１０５と、規制部材１０２と対向する第２の領域１０４を有し、これら第１の領域１０５と前記第２の領域１０４は、１８０度よりも大きな面間角度を有する稜線１０６を介して接続される。【選択図】図６
