A coil alignment device includes: a plate-shaped first jig having a plurality of grooves arranged along a circumferential direction so as to extend toward a radial-direction outer side; and a second jig that can contact with a segment coil inserted in the first jig. Each groove includes a storage portion extending along a radial direction and having a first length so that leg portions of the segment coils can be stored side by side in the radial direction, and a guiding portion extending from the storage portion toward the radial-direction outer side, and has a first shape so that, using, as a fulcrum, one leg portion inserted in the storage portion, the other leg portion is movable toward the storage portion. The second jig is movable to press the segment coil from a radial-direction side and store the other leg portion into the storage portion.
