    • PROBLEM TO BE SOLVED: To provide an adhesive composition having enough adhesive force, even though exposure thereof to light is not avoided.
      SOLUTION: This adhesive composition contains a resorcinol-based compound, a formaldehyde-based compound, a solid component of a latex, and a basic inorganic compound in amounts of 5-15 mass%, 1.7-8 mass%, 80-92 mass%, and 0-1.25 mass% based on a total solid content of the adhesive composition, respectively, wherein the resorcinol-based compound, the formaldehyde-based compound, the solid component of the latex, and the basic inorganic compound are contained in mass percentages satisfying inequality (I): A>-0.175B+0.7C+3.6 [A=(mass% of the formaldehyde-based compound)/(mass% of the resorcinol-based compound)×110/30; B={(mass% of the resorcinol-based compound)+(mass% of the formaldehyde-based compound)}/(mass % of the solid component of the latex); and C=(mass% of the basic inorganic compound)], water is contained in an amount of 25-1,900 pts. by mass based on 100 pts. by mass of the total solid content, and the composition has a pH of 8.5-10.0.
