wherein a surface of the air permeable member projects with respect to a surface of the seat pad located at a closest position to the air permeable member.
2. The seat pad according to claim 1 , comprising:
wherein the covering member covers at least a part of the air permeable member at a boundary surface between the air permeable member and the foamed resin material; and
wherein the covering member is constituted of an impregnation suppressing material having an ingress suppressing function against the foamed resin material higher than that of at least the air permeable member.
3. The seat pad according to claim 1 ,
wherein the surface of the air permeable member projects with respect to the surface of the seat pad located at a closet position to the air permeable member by a distance greater than 0 mm but less than or equal to 5 mm.
4. The seat pad according to claim 1 ,
wherein the air permeable member is an organic fiber body.
5. The seat pad according to claim 1 , wherein the seat pad is a cushion pad having a seating surface, and
the air permeable member is disposed at a forward direction side of the cushion pad.
6. The seat pad according to claim 1 ,

the air permeable member is disposed at a lower portion side of the back pad.
7. The seat pad according to claim 1 ,
wherein the air permeable member is disposed divided into a plurality of portions of the seat pad.
8. A seat pad comprising:
a pad comprising a foamed resin material having at least one hole passing through a part of the pad from a first surface configured to be adjacent an occupant of the seat toward an opposite surface;
an air permeable member having a ventilation function with an outside of the seat pad provided in the at least one hole of the pad, the air permeable member having a portion projecting with respect to a portion of the first surface of the seat pad located closest to the air permeable member; and
a covering member that covers at least a part of the air permeable member, the air permeable member being compressed by the covering member.
9. The seat pad according to claim 8 , comprising:
wherein the covering member covers at least a part of the air permeable member at a boundary surface between the air permeable member and the pad; and
wherein the covering member is constituted of an impregnation suppressing material having an ingress suppressing function against the pad.
10. The seat pad according to claim 8 ,
wherein the portion of the air permeable member projecting with respect to a portion of the first surface of the seat pad located closest to the air permeable member projects by a distance greater than 0 mm but less than or equal to 5 mm.
11. The seat pad according to claim 8 ,
wherein the air permeable member is an organic fiber body.
