Provided in the present invention are an alkaline cellulase variant obtained by using a cellulase having an amino acid sequence exhibiting at least 90% homology with the amino acid sequence represented by SEQ. ID NO:1 and substituting the amino acid residue of the cellullase at (a) position 10, (b) position 16, (c) position 22, (d) position 33, (e) position 39, (f) position 76, (g) position 109, (h) position 242, (i) position 263, (j) position 308, (k) position 462, (l) position 466, (m) position 468, (n) position 552, (o) position 564, or (p) position 608 in SEQ. ID NO:1, or at a position corresponding thereto with another amino acid residue; a gene encoding the variant; a vector containing the gene; a transformant containing the vector; and a detergent composition containing the alkaline cellulase variant. The present invention makes it possible to provide an alkaline cellulase which acts favorably in an alkaline range, and can be mass produced easily because it has a high secretion capacity or enhanced specific activity.
