WThe challenge is to provide an application container capable of reducing an impact force generated by a medicinal solution when the application container is shifted to a downward attitude from an upward attitude. The means for solving the problem is an application container (10) including a bottom wall (20), a body section (30), and a mouth section (80). The body section (30) includes a base portion (40), a reduced diameter portion (50), an interposed portion (60) interposed between the reduced diameter portion (50) and the mouth section (80), and a back-side neck portion (70) interconnecting the interposed portion (60) and the mouth section (80) at a position opposite to the bottom wall (20) across an axis (A) of the mouth section (80) in a direction orthogonal to the axis (A). An inner surface of the first belly-side boundary (31) between the base portion (40) and the reduced diameter portion (50) has a shape curved convexly outward. An inner surface of the second belly-side boundary (32) between the reduced diameter portion (50) and the interposed portion (60) has a shape curved convexly inward. 19
