A metal container with thread capable of preventing such a defect that the strength of a lower end of a mouth part and an upper end of a shoulder part of a container main body is non-resistant to a pressing force in radial and axial directions, and a part of the container may be collapsed or buckled during a capping operation where content is filled into the container and cap is fitted to the container automatically by a machine, characterized in that at least one or more inwardly curving smooth annular recessed parts( 4 ) and at least one or more outwardly curving smooth annular projected parts( 5 ) are formed in an area ranging from the lower end ( 2 a) of the mouth part( 2 ) of the container main body to around the upper end( 3 a) of a tapered shoulder part increasing gradually in radial direction.
