A brush member is caused to properly face any location of a scalp. An electric brush device (1) includes an electric-brush-device main body (2) that is a drive section, and a brush member (3) operated by the electric-brush-device main body (2). The brush member (3) includes a body plate (4) formed of a flexible material, and a plurality of protrusions (5) protrudingly formed on a surface (4S) of the body plate (4). The electric-brush-device main body (2) is provided with a frame (6) that holds the peripheral edge of the body plate (4). The frame (6) is provided so as to be capable of wobbling with respect to the electric-brush-device main body (2) through the support means (7). Accordingly, even if the brush member (3) abuts a scalp (S) in a state not properly facing the scalp, the brush member (3) wobbles with respect to the electric-brush-device main body (2) depending on the abutting state of the protrusions (5), so that the brush member (3) is automatically caused to properly face the scalp (S).
