To obtain a mounting structure of a decorative member at a support capable of simply mounting the member at the support for a television or the like.

The decorative member 14 is formed in a thin strip-like state, and the width of the member 14 is substantially the same as that of a groove 22 formed on a support 12. Thus, the member 14 can be engaged with the groove 22, and is not allowed to deviate in the groove 22 in a vertical direction of a peripheral wall 18. The member 14 has a length or longer for enclosing the surface of the wall 18, and wrapped on the surface of the wall 18 along the groove 22. After the member 14 is passed through a gap 28, the member 14 can be folded at an edge 20A of a locking piece 2. Thus, the member 14 is folded at the edge 20A, the member 14 is thus engaged with the edge 20A, and locked to the wall 18.
