A grommet (10) includes a tapered barrel part (11) and a tape winding spatula part (15). The tapered barrel part (11) includes a large diameter cylindrical portion (12), a small diameter cylindrical portion (13), and an elastic deformation portion (14) disposed between the large diameter cylindrical portion (12) and the small diameter cylindrical portion (13). A fitting groove (12a) to be fitted in a through hole (H) of a panel (P), is formed on the large diameter cylindrical portion (12). A thick walled portion (14c) is formed on an inner side (99) of the elastic deformation portion (14). The tape winding spatula part (15) is connected to the small diameter cylindrical portion (13) and holds a wire harness (W) passed through therein.
