Claim Text:
1. A thin film-manufacturing apparatus comprising: a vacuum chamber; a conveyance system disposed in the vacuum chamber so that an elongated substrate is conveyed from an unwinding position to a winding position; an opening provided facing a conveyance channel in the conveyance system; and a film-forming source for feeding a material to the substrate through the opening, wherein the conveyance system includes a blowing roller having a function of conveying the substrate and a function of supplying a gas for cooling the substrate toward the substrate, and the blowing roller includes: (i) a cylindrical first shell having a cylindrical outer circumferential surface for supporting the substrate and a plurality of first through holes provided along a circumferential direction of the outer circumferential surface as a channel for supplying the gas, the first shell being rotatable in synchronization with the substrate, (ii) an internal block disposed inside the first shell, the rotation of the internal block in synchronization with the substrate being inhibited, (iii) a manifold having a relatively large dimension in a radial direction of the first shell, the manifold being formed, as a space defined by the internal block inside the first shell so as to maintain the gas introduced from outside of the vacuum chamber, to introduce the gas toward the plurality of first through holes within a range of a holding angle defined as an angle formed by a contact portion of the first shell and the substrate with a rotation axis of the first shell at the center, (iv) a clearance having a relatively small dimension in the radial direction, the clearance being formed, as a space formed inside the first shell, to introduce the gas toward the plurality of first through holes outside the range of the holding angle, and (v) a support body extending through the first shell from a first end of the first shell to a second end of the first shell such that at least a portion of the internal block is disposed between an outer surface of the support body and an inner surface of the first shell in a direction perpendicular to the rotation axis.
