To facilitate to apply a base sealant around a prominence uniformly in a high quality is required for a composite material. A sealant applying brush includes a supporting section having a hole opened in a longitudinal direction and a ring shape on a plane orthogonal to the longitudinal direction; and a brush section having hairs implanted in a surface of the ring shape. By supplying such a brush with sealant, and eccentrically rotating the brush such that an inner circumference surface of the hole contacts the prominence of the surface of the workpiece, the sealant can be applied in a circular area around the prominence. |
