The invention relates to a phase module (1) for a power converter (2) comprising at least one switching element (10) and a heatsink (13). In order to improve the cooling properties of a phase module (1), it is proposed that the switching element (10) is connected to the heatsink (13), wherein the connection between switching element (10) and heatsink (13) is a non-detachable connection. The invention further relates to a power converter (2) comprising at least one phase module (1) of this type and a method for producing a phase module (1) of this type, wherein in order to produce a connection between the switching element (10) and the heatsink (13), the switching element (10) is soldered, sintered or glued onto the heatsink (13).
