In a massaging device, a treating section (3) has a body plate (4) formed of a flexible material and a plurality of protrusions (5,6,7) intersecting the surface of the body plate and protruding downwardly. A massaging device main body (2) has a reciprocal drive means that deflects the body plate up and down. The small wall-like protrusions (27) smaller than the third protrusions (7) are provided on the surface of the body plate, and communicating portions communicating the interior with the exterior are provided inside the small wall-like protrusions. A containing portion (26) for shampoo that is communicated with the communicating portions is provided between the massaging device main body and the body plate. A shampoo is applied inside the small wall-like protrusions with the surface of the body plate facing upwardly, and is supplied to the containing portion. The shampoo is whipped correspondingly to the deflection of the body plate while supplied from the communicating portions to perform hair washing and scalp massaging.
