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 20 a disposed at one end of the 8 pieces of the single batteries 20 . A pushing member 14 is formed between the single battery 20 a 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 14 b. The conducting member 17 has through-holes 17 a 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 20 a 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.
