PROBLEM TO BE SOLVED: To provide a ventilation ridge which has high waterproof performance, expands easily a ventilation capacity, and allows installation on a shed roof. SOLUTION: This ventilation ridge 5 is constituted of the first member 10 installed on a roof material 52, a ventilation member 30 installed on the first member 10, and the second member 20 installed to cover those. The first member 10 includes a flat face 11 separated at a prescribed distance X from the roof material 52, and a vertical face 12 positioned on an outer side of an outer wall 51. The ventilation member 30 includes a large number of through-holes penetrated width-directionally. The second member 20 includes a flat plate part 21 in parallel to the flat face 11, the first vertical part 22 abutting on the vertical face 12, and the second vertical part 23 extended downwards toward a position in the outer side of the flat face 11, and formed to allow the position of a lower end to be positioned on a virtual plane including the flat face 11. Thus, the ventilation ridge 5 can be formed into a shape allowing the installation on the shed roof 50, and is easy to expand a vent hole 28 i.e. to expand the ventilation capacity.
