Interior part combined structure

An interior part combined structure obtained by combining a first interior part with a second interior part, the first interior part including a first base and a design material attached to the first base so as to cover at least a part of a surface of the first base, the second interior part including a second base provided so as to cover an end part of the first base,

• wherein:
• the design material is a woven fabric woven by using synthetic resin fibers and side emission type optical fibers as warps or wefts;
• the side emission type optical fibers each include one end part to which a light source is connected, wherein the side emission type optical fibers are straight;
• the one end part includes an end surface facing a light emitting part of the light source;
• the second base includes a bent end part;
• and the bent end part includes an end surface brought into contact with the design material such that an end of the design material, from which the optical fibers extend, is interposed between the bent end part and an end part of the first base;
• and
• the end part of the first base and a light emitting surface of the first base are flat.
