摘要
PROBLEM TO BE SOLVED: To provide a mask which does not make breathing difficult even when worn when breathing becomes rough due to exercise or physical labor or in a hot and humid environment. According to the present invention, the cloth of the mask is attracted by breathing by attaching a tape-shaped core material with elasticity to the lining of the cloth mask at a substantially horizontal position passing between the nostrils and the mouth when worn. Since it prevents the space under the nostrils from being narrowed, it is less likely that breathing will become difficult even when breathing becomes rough due to exercise or physical labor, or when the environment is hot and humid.
