A static mixing device is described, comprising a flow channel and mixing elements which are distributed over the cross section of the flow channel in the form of flow bodies arranged on a wall extending in the direction of flow and which are each delimited by one tapering deflecting surface which is inclined in relation to the wall and originates from a base extending transversally to the direction of flow and by two guide surfaces which protrude from the wall and which converge in an edge extending transversally to the channel axis on the side of the flow bodies which is opposite of the base. In order to provide advantageous mixing conditions for thermally sensitive plastic materials it is proposed that the flow bodies (6) arranged on the channel wall fill out the flow cross section in a projection in the direction of the channel axis (8), with the exception of the pass-through slits (13) between the flow edges (12) obtained between the guide surfaces (10) and the deflecting surface (9), and at least the flow edges (12) between the guide surfaces (10) and the deflecting surface (9) of the flow bodies (6) are rounded off.
