The present invention relates to a foundry core, which has the base form of a hollow body, with the foundry core being formed from a moulding material consisting of a mixture which is formed from a moulding sand and a binder and optionally from additives added to set its properties and a method for its manufacture. The foundry core according to the invention can be easily manufactured. This is achieved as a result of the foundry core being divided into at least two sub-segments and forming elements interacting with one another in a positive-locking manner being provided on the edge sides, with which sub-segments arranged adjacent to one another abut on one another, or in proximity to these edge sides, via which forming elements the sub-segments arranged adjacent to one another are fixed by positive locking immovably against one another at least in one direction.
