Abstract (en)
A method for producing an ear hook member for a mask includes: stretching a stretchable member so that tension occurs in a predetermined direction; superposing a non-stretchable surface material on at least one face of the stretchable member, with the tension being maintained; joining the stretchable member and the surface material together to obtain a joined body; loosening the joined body in the predetermined direction to be in a predetermined loose state where the tension is reduced; and punching the joined body in the predetermined loose state into a predetermined shape.
