A transparent mask equipped with an oxygen supply means, the transparent mask comprising:

• a transparent member configured to be worn on a face and to cover a nose and a mouth;
• a coupling member configured to enable a periphery of the transparent member to be brought in close contact with the face;
• an air inflow port provided on one side of the transparent member and configured to allow air to be introduced into an inside of the transparent member;
• an air discharge port provided on an opposite side of the transparent member and configured to allow air to be discharged to an outside of the transparent member;
• an air discharge means provided in the air discharge port;
• and
• an air inflow pipe with a flexible material, the pipe having one side coupled to the air inflow port,
• wherein the air discharge means includes a discharge flap configured only to allow such that air is discharged to the outside of the transparent member;
• wherein the air inflow pipe has an opposite side branched off into a first branch pipe and a second branch pipe,
• wherein the first branch pipe is provided with a coupling assembly to which an oxygen cylinder is coupled, whereby oxygen is supplied thereto from the oxygen cylinder, and
• the second branch pipe is provided with a second air inflow means, whereby external air is supplied thereto,
• wherein a second air inflow means includes:
