The invention relates to a fan wheel having blades () which are distributed over the circumference and are connected to one another in the circumferential direction via at least one ring. The fan wheel consists of at least three integrally formed segments (I to VII). Said segments comprise at least one respective ring portion () of at least one ring as well as either a blade (II) or at least a portion of the blades. The segments (I to VII) are joined together to form the fan wheel. The ring portions () lie against each other with edges () which form the joining areas () that are disposed transversely with respect to the circumferential direction of the fan wheel. At least one edge () of the ring portion () of each segment (I to VII) is provided with at least one projecting form-fitting part (), and at least one edge () of the ring portion () of each segment (I to VII) is provided with at least one recess () which is at least approximately complementary to the form-fitting part ().
