There is provided an infusion solution for peripheral intravenous administration comprising a multichamber vessel constructed in a connectable manner, which separately houses a sugar solution containing sugars, electrolytes and vitamin B1, and an amino acid solution containing amino acids, electrolytes and a sulfite, whereby the vitamin B1 and amino acids are stably maintained.In the infusion solution for peripheral intravenous administration, the sugar solution contains calcium gluconate, contains no greater than 1.4 g/L sodium lactate, has a pH of 4.0-4.7 and has a titratable acidity of 2-4, the amino acid solution contains 4.0-8.0 g/L sodium lactate, contains no calcium gluconate, has a pH of 6.8-7.2, contains free L-cysteine as cysteine and contains 0.05-0.2 g/L sodium hydrogen sulfite, and after the sugar solution and amino acid solution have been mixed, the infusion solution has a pH of 6.5-7.1 and a titratable acidity of 5-10.
