PROBLEM TO BE SOLVED: To obtain a solid detergent composition improved in solubility, especially low-temperature solubility even if containing a hardly dissolvable anionic surfactant, and stabilized in qualities including color tone and smell. SOLUTION: This solid detergent composition is characterized by comprising an 18C unsaturated fatty acid alkoxylate-type nonionic surfactant with the cis-form/trans-form mass ratio of (30:70) to (99:1), an unsaturated fatty acid ester alkoxylate-type nonionic surfactant and an unsaturated alcohol alkoxylate- type nonionic surfactant.
