A screw hole seal structure seals a screw hole () in molding a fiber-reinforced resin member () in which an insert member () provided with the screw hole () is integrally incorporated. In the structure, a screw member () is tightened in the screw hole (). In the structure, an elastic seal member () is compressed within the screw hole (), in an axial direction of the screw member (), and is therefore deformed radially outwards by compression force that is created by tightening of the screw member (), and an air-tight state of the screw hole () is maintained by deformation of the elastic seal member ().
