Claim:
1. A substrate transport roller which is installed rotatably around a specific center axis and transports a substrate in a deposition device which executes a deposition treatment on a surface of the substrate, comprising: a center-section segment which is installed in a center portion in an axial direction along the center axis, and comprises a first outer-circumferential surface; a pair of end-section segments respectively positioned at outer sides of the center-section segment in the axial direction, each respectively comprising a second outer-circumferential surface and a third outer-circumferential surface in a cylindrical shape which are concentric with the center axis, the second outer-circumferential surface and the third outer-circumferential surface each having a diameter larger than the diameter of the first outer-circumferential surface in order to transport the substrate by rotating in a condition that the substrate is in contact with the second outer-circumferential surface and the third outer-circumferential surface, and in order to prevent the substrate from contacting the first outer-circumferential surface; a center-section temperature raising/lowering mechanism which varies temperature of the center-section segment, including heating of the center-section segment; and a both-end-section temperature raising/lowering mechanism which varies temperature of each of the pair of end-section segments, including heating of the pair of end-section segments, independently from the center-section segment.
