Abstract: A deposition apparatus includes: a first moving apparatus that causes a stepwise change in a relative position between a deposition mask and a substrate in a direction parallel to one surface in a condition in which the deposition mask and the substrate are spaced apart from each other; and a gap adjustment apparatus that, before a start of relative movement between the deposition mask and the substrate by the first moving apparatus, causes relative movement between the deposition mask and the substrate in a direction spacing the deposition mask and the substrate apart and adjusts a gap between the deposition mask and the substrate, and that, when the first moving apparatus has stopped the relative movement between the deposition mask and the substrate, causes relative movement between the deposition mask and the substrate in a direction in which the deposition mask and the substrate approach each other and adjusts the gap between the deposition mask and the substrate.
