To provide a metal member with a three-dimensional regular skeleton structure with high porosity, low pressure loss of passing fluid and excellent strength.SOLUTION: Provided is a metal member 10 with a three-dimensional regular skeleton structure with a porosity within a range of 50% or more and 95% or less. The three-dimensional regular skeleton structure has a skeleton 12 and a plurality of pores 11 extending in a first direction. A lamination structure, in which pore rows 15 with the pores 11 and the skeleton 12 arranged alternately are laminated periodically, is formed on a cross section orthogonal to the first direction. On the pore rows 15 adjacent to each other in a lamination direction, the phases of the pores 11 and the skeleton 12 are shifted.SELECTED DRAWING: Figure 2 【課題】空隙率が高く、且つ、通過する流体の圧力損失が低く、強度に優れた３次元規則骨格構造を有する金属部材を提供する。【解決手段】空隙率が５０％以上９５％以下の範囲内とされた３次元規則骨格構造を有する金属部材１０であって、前記３次元規則骨格構造は、骨格１２と第一方向に延在する複数の気孔１１とを有し、前記第一方向に直交する断面において、気孔１１および骨格１２が交互に配列された気孔列１５が、周期的に積層された積層構造が形成されており、積層方向に隣接する気孔列１５同士において、気孔１１および骨格１２の位相がズレていることを特徴とする。【選択図】図２
