A threaded metal container capable of improving strength (neck portion transverse rigidity) in a direction perpendicular to a container axis at a neck portion composed of a mouth portion and a shoulder portion. The container includes a body portion, a shoulder portion, and a mouth portion. The mouth portion includes a base portion connected to an upper end of the shoulder portion, and a skirt valley portion, a skirt portion, and a threaded portion, which are above the base portion. The base portion 8 includes a protruding portion protruding radially outward and has a diameter gradually increasing downward from the skirt valley portion and a bead portion radially inwardly protruding and smoothly curving downward from the protruding portion. The bead portion circumferentially extends in a linear or dotted pattern. The bead height between the protruding portion and the bead portion in the direction perpendicular to the container axis is 0.1 to 0.6 mm.
