Estimating the term…
A powder composition includes a polyamide powder (A) and an inorganic reinforcing material (B), in which the polyamide powder (A) has a D50 particle diameter of 1 μm or more and 100 μm or less and a sphericity of 80 or more and 100 or less, the inorganic reinforcing material (B) has an average major axis diameter of 3 μm or more and 300 μm or less and an (average major axis diameter)/(average minor axis diameter) ratio of 1 or more and 15 or less, and the inorganic reinforcing material (B) is contained at an amount of 5% by weight or more and 60% by weight or less relative to the total weight of the powder composition.
