PROBLEM TO BE SOLVED: To provide a cylindrical battery with characteristics will not decreasing even when it is vibrated, and in which a plurality of current-collecting tabs 3 are drawn out of the positive and negative electrodes of a robed electrode body 2 contained in a battery can 1, so that electric power generated by the electrode body 2 can be taken out from a pair of electrode terminal parts via the plurality of current-collecting tabs 3. SOLUTION: In the cylindrical battery, a shaft member 4 is disposed at the center of the rolled electrode body 2, with both ends 41 and 41 of the shaft member 4 protruding from the electrode body 2. Tab holding plates 7 and 7 made of insulating material are attached to both ends 41 and 41 in a manner precluding relative rotation. A plurality of through holes 71 enabling one current- collecting tab 3 to pass therethrough are cut in each of the tab holding plates 7 and 7. Each current-collecting tab 3 is passed through different through holes 71 and connected to electrode terminal mechanisms 5 and 6 at its end.
