To provide a cleanser which is used for electronics, has more improved cleansability, rinsability, and corrosion resistance than those of conventional cleansers, and little gives loads to the environments.

This cleanser for the electronics is characterized by comprising the following (A) to (F). (A): one or more hydrophobic compounds selected from the group consisting of 8 to 24C hydrocarbons and alkyl aliphatic carboxylates totally having 4 to 16 carbon atoms, (B): a 8 to 26C alcohol having a melting point of ≤20°C, (C): a glycol ether represented by the general formula (1): R1-O-(XO)n-R2 [R1 is a 4 to 8C hydrocarbon group; R2 is H or a 1 to 4C hydrocarbon group; X is a 2 to 4C alkylene; (n) is an integer of 1 to 4], (D): a corrosion-resistant agent, (E): a surfactant, and (F): water.
