Interdental brush

The present invention relates to an interdental brush, having a bristle support stem (18) defining a longitudinal direction (22) with an elongated support core (24), a bristle field (26) with bristles (20) protruding from the bristle support stem (18) and a neck element (32) connecting the support core (24) to a handle (16'). The handle (16'), the support core (24) and the neck element (32) are integrally made of a first plastic component made of hard material. Furthermore, a second plastic component made of soft material is applied to the support core (24) in the form of an integral layer (28) with bristles (20) protruding from it. The integral layer (28) made of soft material is preferably applied to the support core (24) flush with the neck element (32). The injection point (51, 51'') of the second plastic component is located at the front end of the handle (16') facing the neck element (32).
