A surface extraction method capable of improving accuracy of extraction of surfaces of an object, a surface extraction device, and a program are proposed. A voxel space that is divided into voxels having a lattice shape, and whether or not object constituting voxels that constitute an object which is shown in the voxel space is investigated in units of voxel rows of the voxels. Ends of the continuous object constituting voxels in the voxel rows are extracted as surfaces of the object. Straight-line rows are used as units, and intermediate portions of continuous constituting regions in the straight-line rows are ignored. Thus, even when a region that does not constitute the object exists inside the object, the region that does not constitute the object can be prevented from being falsely extracted as a surface of the object without investigation of the same region two times or more.
