PROBLEM TO BE SOLVED: To provide a cylinder lock in which a plurality of disc tumblers are inserted into the same tumbler mounting hole, and which prevents a malfunction between the disc tumblers. SOLUTION: The cylinder lock is formed by turnably inserting a plug 3 consisting of a plurality of disc tumblers 2 inserted into the tumbler mounting hole 1 into a cylinder case 4; and the disc tumblers 2 are inserted into the same tumbler mounting hole 1, and held in an initial position with being urged by the same compression spring 5 housed in the tumbler mounting hole 1. A partitioning protrusion 6, which prevents the state of adhesion between the adjacent disc tumblers 2 by forming a proper gap between the adjacent disc tumblers 2, is protrusively provided in the tumbler mounting hole 1.
