    Abstract: The disclosure relates to an actuating apparatus (1) for a vehicle door handle arrangement, such as an inner door handle arrangement. The actuating apparatus (1) is manufactured in a multi-component injection molding method, such as a two-component injection molding method. The actuating apparatus (1) includes a carrier portion (4) made from a first plastic material and a decorative layer (5), in particular integrally connected to the carrier portion (4), made from a second plastic material. When used as intended, the actuating apparatus (1) comprises a first region (9), which faces away from the user in the resting position of the actuating apparatus (1) and at least regionally represents the rear side of the actuating apparatus (1) to be rearwardly engaged by the user when actuating the actuating apparatus (1), and a second region (10), which faces the user and at least regionally represents in particular the visible region of the actuating apparatus (1) in its resting position, in the first region (9) of the actuating apparatus (1), the decorative layer (5) completely covers the carrier portion (4), and, on a surface of at least 50% of the second region (10) of the actuating apparatus (1), the decorative layer (5) covers the carrier portion (4).
