The invention relates to a turbine housing (10) for an exhaust gas turbocharger of an internal combustion engine with at least one spiral channel (12a), which can be coupled with an exhaust gas flow of an exhaust tract of the internal combustion engine, and an accommodating space (14) for a turbine wheel (16), which is disposed downstream from the at least one spiral channel (12a) and can be acted upon with the exhaust gas of the internal combustion engine, which can be passed through the at least one spiral channel (12a), wherein this comprises at least one partial housing (18), comprising the at least one spiral channel (12a), and a housing module (20), which is fastened at the partial housing (18) and has guide vanes (22), which are disposed upstream from the accommodating space (14), and an entrainment surface (24) for a bearing box (26) of the exhaust gas turbocharger. The invention furthermore relates to an exhaust gas turbocharger with a turbine housing (10) and to a method for producing a turbine housing (10).
