PROBLEM TO BE SOLVED: To secure strength of a box and to reduce weight of it concerning the box for a control device of an electric rolling stock arranged on the electric rolling stock and in which control equipment is stored and its manufacturing method. SOLUTION: This box for the control device of the electric rolling stock is arranged on the electric rolling stock, stores the control equipment of the electric rolling stock, has inspection ports to inspect the control equipment on the left and right side surfaces in the travelling direction, comprises a top plate 5 of a top surface, a bottom plate 6 of a bottom surface, each of side plates 7, 8 arranged on fore and aft in the travelling direction of the electric rolling stock and connecting the top plate 5 and the bottom plate 6 and the left and right partition plates 9, 10 partitioning the area between the top plate 5 and the bottom plate 6 into left and right of the travelling direction and connecting the top plate 5, the bottom plate 6 and each of the side plates 7, 8 to each other, and the thickness of each of plates 5 to 10 is determined in consideration of weight of the control equipment and vibration at the travelling of the electric rolling stock. In this constitution the plate thickness of the top plate 5, the bottom plate 6 and each of the side plates 7, 8 is made thinner by 30 to 50% than the thickness of the left and right partition plates 9, 10.
