A grommet which passes through and is held by a hole formed in a panel includes a grommet portion and a silencer. The grommet portion is made of an elastic material, and has a large diameter portion having a rib portion, a small diameter portion, and an opening penetrating the large diameter portion and the small diameter portion. The silencer includes a noise insulating portion made of a hard noise insulating material, a front end portion of the noise insulating portion being inserted into the grommet portion, a recess portion for engaging the rib portion formed on the noise insulating portion, and a noise absorbing portion made of a soft noise absorbing material. The noise insulating portion and the noise absorbing portion are integrally formed, and a wire insertion hole is formed so as to penetrate the noise insulating portion and the noise absorbing portion.
