Abstract: To provide an ear protecting material which reduces pain caused by an ear string when a mask is worn, allows mask attaching/detaching action to be repeatedly performed, eliminates a troublesome working procedure at an ear string part when attaching a mask, and prevents the head and neck movement to be restricted even in such a state as the mask is not worn.SOLUTION: In order to disperse the pressure at a part against which a mask ear string abuts by a cushioning function, an ear protecting material is disposed behind an auricle root. The ear protecting material is formed in a C-shape in a major axis direction along the outline of the auricle root, and its upper end covers an upper part of the auricle root and its lower end covers a lower part thereof. The ear protecting material is stuck to the skin behind the auricle by using an adhesive so as to prevent the ear protecting material to fall down due to repetition of mask attaching/detaching and to prevent the head and neck movement to be restricted in such a state as the mask is not worn. A shallow vertical groove is formed on the back face of the ear protecting material, and thereby the mask ear string is locked to the ear protecting material so as not to deviate in the movement.SELECTED DRAWING: Figure 4
