Abstract

A battery module includes a plurality of cells and a fixing portion that fixes each of the plural cells. With support rigidity k of the fixing portion and mass m of the cell, k/m of two or more sets of the cell and the fixing portion is reference k/m. When a value of tan δ as a loss factor of the fixing portion is x, a minimum value k<min> of k is k<min> = 5.184 x 10<9>(1/x)<2>(1/m)<3>, a maximum value k<max> of k is k<max> = 482.2531x<2>m<5>, and k<min> < k<max>, k of the reference k/m falls within a range of k<min> ≤ k ≤ k<max>. By using the maximum k/m that is greater than the reference k/m and the minimum k/m that is less than the reference k/m, the dispersion D of (the reference k/m)/(the reference k/m), (the maximum k/m)/(the reference k/m), and (the minimum k/m)/(the reference k/m) satisfies 0.2 < D < 550.
