An electrode tip magazine for a spot welder that does not interfere with the welding gun is provided. The magazine includes a magazine body formed with a storage part slidably aligning and storing a plurality of electrode tips therein, one end of this storage part serving as an externally opened supply port, a push-out member disposed to be freely slidable between both ends inside the storage part, a pulley disposed at a position adjacent to the supply port of the magazine body, a spiral spring disposed at a position at the other end of the storage part of the magazine body, and a wire connecting a distal end of the spiral spring and the push-out member with an intermediate portion thereof being wound around the pulley so as to always pull the push-out member toward the supply port by a biasing force of the spiral spring.
