Abstract
In a case where an FSSS average particle size of a tungsten-containing powder as obtained by an FSSS method is defined as a (μm) and a density TD, which is an inverse number of a tap volume of the tungsten-containing powder, is defined as p (g/cm3), a relational expression of p≥0.37a+7.04 is satisfied when a range of the FSSS average particle size a is 0.5 μm≤a≤5.0 μm.
