Zusammenfassung:A coolant composition includes a viscosity improving agent and a base. The viscosity improving agent includes at least one selected from an anionic surfactant represented by the following Formula (1) of R10-(R20)m-S03M and at least one selected from the group consisting of a cationic surfactant represented by the following Formula (2) and an amphoteric surfactant represented by the following Formula (3) or Formula (4). The base is formed of water and/or at least one alcohol selected from the group consisting of a monohydric alcohol, a dihydric alcohol, a trihydric alcohol, and a glycol monoalkyl ether, in which a shear viscosity is 8.5 mPa.s or higher at 25°C and is 2.0 mPa.s or lower at 100°C.
