    摘要： A flange 37b of a cap case 37 is provided with protrusions 37c that, before being swaging, project upward from the flange 37b. When the flange 37b is swaged along an upper surface of the cap 3, the protrusion 37c projects along the upper surface of the cap 3 from the flange 37b toward a center of the cap 3. The cap case 37 is welded to the cap 3 by friction stir welding at a welding portion 37d located at a substantially center of the protrusion 37c. The protrusions 37c are formed approximately in a letter-T shape that is symmetric left and right, and width W2 of a connecting portion 37r in a cap circumferential direction is smaller than the maximum width W1. The rigidity of the connecting portion 37r against deformation is reduced by forming a portion with small width W1 at the connecting portion 37r.

    摘要： The present invention provides a secondary battery module capable of securing safety at a time of abnormal battery operations by using a film-type secondary battery. A module 30 is provided with 8 pieces of single batteries 20 each using a laminate film as its battery container. The 8 pieces of single batteries are disposed in a layer-stacked state. A conducting plate 17 is placed in a manner to face one single battery 20a disposed at one end of the 8 pieces of the single batteries 20. A pushing member 14 is formed between the single battery 20a and conducting plate 17. A conducting plate 18 is disposed on a side of the conducting plate 17 opposite to the pushing member 14. The pushing member 14 has projected portions 14b. The conducting member 17 has through-holes 17a formed so that the projected portions are able to pass through. The conducting plates 17 and 18 are coupled by a coupling portion 21. When any one of the single batteries 20 and single battery 20a expands at a time of abnormal battery operations, the projected portions pass through the through-holes to break off the coupling at the coupling portion 21.
