PROBLEM TO BE SOLVED: To provide a mortar having a groove shape which enables downsizing the mortar itself, and a beverage manufacturing apparatus equipped with the same.SOLUTION: In a mortar 2B, a first rubbing face includes a shear groove having a curve profile which extends toward an outer periphery from a rotation center side, and a second rubbing face 360a includes a shear groove 360b having a curve profile which extends the outer periphery from the rotation center side, and both shear grooves are not overlapped in a state that the first rubbing face and the second rubbing face 360a are overlapped. A first mortar 350 and/or a second mortar 360 further include a feed groove 360b having a curve profile which extends toward the outer periphery from the rotation center side. The first mortar 350 and/or the second mortar 360 further include a cylindrical inner peripheral surface 361 which defines a charging port for charging a pulverization object at a midship part, and a pulling groove 360c which opens toward the rubbing face 360a from the inner peripheral surface 361, and a terminal of the pulling groove 360c is coincident with an initial point of a fourth groove.SELECTED DRAWING: Figure 34【課題】臼の小型化を可能とする溝形状を備えた臼、およびそれを備えた飲料製造装置の提供。【解決手段】第１擦り合せ面は、回転中心側から外周に向けて延びる曲線形状を有するせん断溝を含み、第２擦り合せ面３６０ａは、回転中心側から外周に向けて延びる曲線形状を有するせん断溝３６０ｂを含み、第１擦り合せ面と第２擦り合せ面３６０ａとを重ね合せた状態において、せん断溝とせん断溝とは重なり合わず、第１臼３５０及び／又は第２臼３６０は、回転中心側から外周に向けて延る曲線形状を有する送り溝３６０ｂをさらに含み、第１臼３５０および／または第２臼３６０は、中央部に粉砕対象物を入れる投入口を規定する円筒形状の内周面３６１と、内周面３６１から擦り合せ面３６０ａに向けて開口する引き込み溝３６０ｃと、をさらに含み、引き込み溝３６０ｃの終端は第４溝の始点と一致している臼２Ｂ。【選択図】図３４
