The heat-retaining and humidity-retaining effects of conventional masks are limited to the periphery of the nose and mouth, and therefore, the ears are usually cold and numb. This mask is provided with a three-dimensional space having size, roundness, deepness, etc. suitable for wrapping the lower half of the facial surface and the ears, thereby guiding exhaled air to the ears. Cord-like ear hook parts to be hooked on the ears are mounted to a mask body.
