PROBLEM TO BE SOLVED: To provide an ink storage container economically comprising a light shielding layer preventing external light from entering the ink storage container even when a crack is formed in a metal layer constituting a bag body. SOLUTION: The ink storage container 100 includes the bag body 110 storing ultraviolet curable ink. The bag body 110 is formed in bag shape by heat-welding the peripheral edges of rectangular laminated sheet bodies 111a, 111b. Each of the laminated sheet bodies 111a, 111b has an outer resin layer 113 arranged on the upper side of a metal layer 112 made of aluminum foil. The outer resin layer 113 is composed of a first outer resin layer 113a and a second outer resin layer 113b. A black light shielding layer 114 made of carbon black is formed on the surface of the second outer resin layer 113b out of the first and second outer resin layers. A lower resin layer 115 is arranged on the lower side of the metal layer 112. The lower resin layer 115 is composed of a first inner resin layer 115a and a second inner resin layer 115b.
