PROBLEM TO BE SOLVED: To provide a roof ventilation member which improves a ventilation performance and is capable of preventing rain water from penetrating into an attic space. ! SOLUTION: A fourth slope 13a of a lower plate 13 is mounted over tiles 116 on a top stage of a roof material 101 covered by a roofing 119, and a ventilation member covers a ventilation hole 103 which is formed in a joint part 102 between a vertical wall surface 100 of a purline and the roof material 101, and is fixed to the roof material 101 by nails 15. A folded surface 11a of an upper plate is abutted to the wall surface 100, fixed by nails or the like and covered by siding 118 or the like. The ventilation member covers the ventilation hole 103, thereby forming a ventilation passage B from the ventilation hole 103 through a fourth ventilation opening 13c, a first ventilation space and a second ventilation space to a first ventilation opening and a second ventilation opening as illustrated by an arrow of a solid line.
