PROBLEM TO BE SOLVED: To provide a mask having a high close fitting property with a simple structure. SOLUTION: In this mask comprising an ear cord on a mask body, a means of providing a triangular angular piece formed by connecting surface and reverse cloths in one angle of the vertical center line-side upper edge of the mask body in the state where the mask body is laterally equally folded is used. Accordingly, since the upper edge center of the mask body is made in substantially V-shape by the formation of the angular piece, its shape is matched to the root of nose, and the close fitting property extending from the root of nose to the cheek is enhanced. |
