An apparatus for manufacturing a thin-film laminate prevents loosening of a strip-shaped flexible substrate at the time of conveying or misalignment of the strip-shaped flexible substrate with respect to a winding roller at the time of winding. In the apparatus, a strip-shaped flexible substrate in a lateral direction is conveyed by positioning longitudinally the width direction of the strip-shaped flexible substrate wound in a roll shape. The apparatus includes a deposition device having a deposition chamber for forming a thin film on the strip-shaped flexible substrate, a winding roll for winding a thin-film laminate, and an adjustment roller to prevent a loosening or misalignment of the strip-shaped flexible substrate between a pair of grip rollers and the winding roll, and the pair of grip rollers arranged in front of the adjustment roller to convey the thin-film laminate while maintaining a given height.
