PROBLEM TO BE SOLVED: To provide an agent having high anti-VRSA (vancomycin-resistant staphylococcus aures) activities and low side effects on a human body. SOLUTION: The anti-VRSA agent contains a salt of a heteropolyacid ion represented by general formula [XY<SB>y</SB>W<SB>12-y</SB>O<SB>40-z</SB>(O<SB>2</SB>)<SB>z</SB>]<SP>p-</SP>(I), [XY<SB>y</SB>W<SB>18-y</SB>O<SB>62-z</SB>(O<SB>2</SB>)<SB>z</SB>]<SP>p-</SP>(II), [äXY<SB>y</SB>W<SB>12-y</SB>O<SB>40-z-3</SB>(O<SB>2</SB>)<SB>z</SB>}<SB>2</SB>O<SB>3</SB>]<SP>p-</SP>(III), [äXY<SB>y</SB>W<SB>12-y</SB>O<SB>40-z-2</SB>(O<SB>2</SB>)<SB>z</SB>}<SB>2</SB>O<SB>2</SB>]<SP>p-</SP>(IV) or [äXY<SB>y</SB>W<SB>12-y</SB>O<SB>40-z-3</SB>(O<SB>2</SB>)<SB>z</SB>}<SB>4</SB>O<SB>6</SB>]<SP>p-</SP>(V) and aβ-lactam-based antibiotic as active ingredients.
