PROBLEM TO BE SOLVED: To provide a method for providing a bone cement which can be easily, safely and promptly provided. In a device including a first hollow cylindrical container (200) and a second hollow cylindrical container (300), and a vessel (210) provided in the first container, in which a monomer liquid (211) is stored. Producing a bone cement from at least two starting components of A hollow cylindrical first container 200 in which a vessel 210 for a monomer liquid as a first starting component can be stored, a first internal space 320 in which a bone cement powder 321 as a second starting component can be stored, and a monomer liquid. A hollow cylindrical second container 300 including a second internal space 330 that can be conveyed therein, a fluid conducting and conveying means 340 provided between the first internal space and the second internal space, and the first container and the second container. The containers are axially connected to each other.
