摘要： According to the present invention, a multilayer tablet showing suppressed layer separation and a production method thereof are provided. A concave portion having a depth of not less than 0.1 mm Ka is formed on at least one surface Sa of the both front and back surfaces (Sa, Sb) of a multilayer tablet. Particularly, a multilayer structure obtained by, in tableting, forming a convex portion for forming the concave portion on at least the upper punch, and preliminarily compressing all layers in the multilayer tablet with the upper punch to form a concave portion having the same shape with a depth of not less than 0.1 mm on the upper surface of all layers, wherein the powder materials of the next layer are protruding into the concave portion, is a preferable embodiment.
