PROBLEM TO BE SOLVED: To provide an underwater mask provided with buckles where adjuster members can be mounted to base parts by sliding and engaging parts can be pressure-welded to the surface of a strap by the elastic deformation of the adjuster members. SOLUTION: The undewater mask 10 is provided with the buckles 10 for connecting the head strap 35 at the side parts of a lens frame 31. Each buckle 10 consists of the base member 11 and the adjuster member 20. The base member 11 has a shaft part 16 for set the strap around, and the adjuster member 20 is inserted from the shaft part side toward an end part on a side opposite to it in a state where it can be pulled out. The adjuster member 20 has a fitting part 21, which is provided with an engaging part 24 pressing to the strap set around the shaft part 16 by the elastic deformation of a spring part 21e. The fitting part has a flat first insert-holding part 21a and a second insert-holding part 21b separated from and parallel to this first insert-holding part 21a, and a part of the base member is fitted between both of these insert-holding parts to be fixed detachably.
