The present invention provides a robust metal lamination-shaped object containing aluminum and having no defect. A metal powder used for forming this metal lamination-shaped object is an aluminum-based powder having a volume-based 50% particle diameter larger than or equal to 10 &#x3bc;m and smaller than 100 &#x3bc;m when a particle diameter distribution is measured by a laser diffraction-scattering method, a specific surface area smaller than or equal to 0.5 m/g, and an oxygen amount larger than or equal to 3 mg/mand less than or equal to 10 mg/mper unit surface area. A relationship between a hydrogen amount (X ml in standard state) per 100 g of the aluminum-based powder and a specific surface area (Y m/g), and a relationship between the hydrogen amount (X ml in standard state) and an oxygen amount (Z wt %), are respectively in accordance with formulas: X/Y&#x3c;151 and Z/X&#x3e;0.0022. A metal lamination-shaped object, that is lamination-shaped by a three-dimensional lamination-shaping apparatus in a powder bed fusion type using the above metal powder, has a hydrogen amount less than or equal to 3 ml in standard state per 100 g, and a relative density more than or equal to 99%.
