PROBLEM TO BE SOLVED: To improve heat shield performance of a joint part of an interior finish material crossing with a support member by simple construction.SOLUTION: An interior structure 1 includes an interior finish material 2 having a first joint part 21a traveling in the first direction and a second joint part 21b traveling in the second direction crossing with the first direction, and a plurality of support members 3 extended in the first direction, joined to a reverse surface of the interior finish material 2, supporting the interior finish material 2 and at least partially covering the first joint part 21a, and is provided with a joint part backing material 10 installed between mutually adjacent first and second support members 3a and 3b among the plurality of support members 3. The joint part backing material 10 comprises a flat surface 11 arranged along the reverse surface of the interior finish material 2 and covering the second joint part 21b and a pair of rising surfaces 12 formed by respectively rising both ends of the flat surface 10 along a side surface of the first and second support members 3a and 3b and fixing the joint part backing material 10 to the first and second support members 3a and 3b. |
