A window 30 is a two-color molding comprising a transparent section 32 and
a frame section 31 integrated with the transparent section 32, the frame
section 31 and the transparent section 32 are formed with a first material
and a second material respectively, and the first material is a
thermoplastic resin with the linear thermal expansion coefficient in the
MD direction lower by 1.times.10.sup.-5 to 3.times.10.sup.-5 (mm/(mm.K))
than that of the second material, and also with the MD/TD ratio for the
linear thermal expansion coefficient in the range from 0.6 to 1.
