Claim Text:
1. A battery module, comprising: a flat battery including a positive electrode active material layer, an electrolyte layer, and a negative electrode active material layer layered in this order in a layered direction, the flat battery having a current-taking-out surface from which electric current is taken out, the current-taking-out surface providing a major surface of the flat battery and facing in the layered direction; a flat electrode tab having a major surface thereof opposite to the current-taking-out surface in the layered direction, the flat electrode tab having an electrode-taking-out section extending from an edge of the major surface of the flat electrode tab in a direction perpendicular to the layered direction for connection to a bus bar; a flat electron-conductive elastic member arranged between the major surface of the flat electrode tab and the current-taking-out surface of the flat battery, the elastic member having a first major surface being in surface contact with the major surface of the flat electrode tab, and a second major surface being in surface contact with the current-taking-out surface, the second major surface of the elastic member supporting the flat battery in the direction perpendicular to the layered direction; and a packaging case covering the flat battery, the flat electrode tab, and the electron-conductive elastic member, wherein the battery module is installed in a vehicle and subject to vibration of the vehicle, and wherein the elastic member has a Young's modulus in a range from 0.01 to 0.30×10
