PURPOSE: A pressure indicator and an assembly method thereof are provided to reduce an assembly cost about a gauge case which comprises a lower case and an upper case and improve assembly ability according to the assembly of the gauge case. CONSTITUTION: A pressure indicator includes a gauge case (100) and a pressure indicator (200). The gauge case includes a lower case (110) and an upper case (120). The lower case includes a fixing part (112) which is connected to a pressure container (2a), is combined with an upper side of an adapter (130) in which a through hole (32) is formed inside, and is extended in an upper direction along a circumference direction. The upper case is positioned in the upper part of the lower case, is combined with the lower case, and forms a sealing area. The pressure indicator is accommodated inside of the gauge case, is connected to the through hole, and displays a pressure of a pressure container which is delivered through the adapter.
