OG exemplary drawing
 
1. A powder to be used in an additive manufacturing method involving performing shaping a structural body through irradiation with laser light, the powder comprising:
an inorganic compound serving as a base material to form a eutectic in the structural body; and
an absorber having a higher light-absorbing ability for the laser light than the base material,
wherein a content of the base material in the powder is 90 vol % to 99.5 vol %,
wherein a content of the absorber in the powder is 0.5 vol % to 10 vol %, and
wherein the absorber is a particle comprising at least one selected from the group consisting of Ti2O3, TiO, SiO, ZnO, antimony-doped tin oxide (ATO), indium-doped tin oxide (ITO), MnO, MnO2, Mn2O3, Mn3O4, FeO, Fe2O3, Fe3O4, Cu2O, Cr2O3, CrO3, NiO, V2O3, VO2, V2O5, V2O4, and Co3O4.
 
6. A method of manufacturing a structural body comprising repeating:
a step (i) of placing the powder of claim 1 at a site to be irradiated with the laser light; and
a step (ii) of irradiating a predetermined site of the powder with the laser light to sinter, or melt and solidify the powder.
