Provided are: a method for evaluating the genomic instability of pluripotent stem cells efficiently and with a high degree of reliability; a method for removing, from a culture of pluripotent stem cells to be evaluated, pluripotent stem cells which are identified as being genomically instable by said evaluation method; and a synthetic peptide that can be used in these methods.　The methods provided by the present invention include: preparing a culture of target pluripotent stem cells; investigating the level of expression of calreticulin in pluripotent stem cells in said culture; and identifying the genomic stability or genomic instability of said stem cells on the basis of said level of expression of calreticulin.
