The invention relates to the technical field of ships and provides a cargo hold passage of a container ship. The cargo hold passage of the container ship comprises a plurality of cargo hold platforms and a plurality of spiral staircases, the cargo hold platforms are hierarchically arranged in a cargo hold, each spiral staircase is arranged between every two adjacent cargo hold platforms, the height of each spiral staircase layer is identical to that of a container, the spiral staircases are positioned among air ducts, and the spiral staircases in a same vertical plane are identical in the spiral direction. The cargo hold passage of the container ship has advantages that the safe and comfortable passage is provided for sailors in a limited space of the container ship without affecting the air ducts and walkway space of the cargo hold platforms, and the problem of going up and down is solved effectively for personnel while high economy is realized, so that the cargo hold passage is worthy of popularization and application.
