Mask

The invention provides a mask which is easy for a wearer to breathe and can improve fit with the face. The mask (1) has: an up-down direction (X) extending up and down in a worn state, and an intersecting direction (Y) orthogonal to the up-down direction; a covering part (10) which covers the mouth of the wearer and which is composed of a film having a light transmittance of 80% or more; a support part (20) that supports the cover part; and a hooking part (30) which is connected with the supporting part and is hung on the ear of the wearer. The cover portion has an outer edge (11) extending in the vertical direction at an end edge of the cover portion in the intersecting direction. The support section has a side support section (21) that covers at least a part of the outer edge of the cover section. The air permeability of the supporting part is higher than that of the covering part. The rigidity of the cover portion is higher than that of the support portion. 本发明提供一种佩戴者易于呼吸且能够提高相对于脸的贴合性的口罩。口罩(1)具有：在佩戴状态下沿上下延
