A pressure container (1) includes a metal socket (3) and a CFRP layer (12) that contacts the metal socket (3). A metal oxide layer (50) is formed on a first contact area where the socket (3) contacts the CFRP layer (12). The socket (3) may be made of aluminum or aluminum alloy, and the oxide layer (50) may be formed by anodizing the socket (3). |
