Abstract: In an aligning device, in plan view, a first recess of a first transfer jig allows an entire region of a second recess of the first transfer jig to be situated within the first recess of the first transfer jig by a predetermined interval. A first recess of a second transfer jig allows an entire region of a second recess of the second transfer jig to be situated within the first recess of the second transfer jig by a predetermined interval. When the first transfer jig and the second transfer jig overlap each other, the first recess of the second transfer jig allows the entire region of the second recess of the first transfer jig to be situated within the first recess of the second transfer jig by a predetermined interval. With the alignment object being transferred into a cavity of the first transfer jig, by causing the first transfer jig and the second transfer jig to overlap each other, the alignment object is transferred from the cavity of the first transfer jig to a cavity of the second transfer jig.
