It is an object to provide a linear motor armature which can simplify the motor structure and reduce the size while reducing the deformations of the board, the can and the frame, and a linear motor using that armature. The linear motor armature comprises an armature coil ( 11 ) fixed on the two side faces of a board ( 12 ), and a sealed body including a can ( 2 ) and a frame ( 3 ) and disposed to cover the armature coil ( 11 ), and a coolant is fed around the armature coil ( 11 ) to cool the same. The armature coil ( 11 ) is adhered and fixed to the board ( 12 ) and is assembled with the frame ( 3 ). After this, a brace ( 9 ) is arranged between the can ( 2 ) and the frame ( 3 ), and the can ( 2 ) and the brace ( 9 ), and the frame ( 3 ) and the brace ( 9 ) are individually jointed to each other by welding them.
