<p>Provided is a secondary battery in which short-circuiting of a battery container and a nut or a bolt of a fastening structure does not occur, even if the nut or the bolt are loosened. The dimensions of a gap between at least one of either a head part (29a) of the bolt (29) or the nut (128B) of the fastening structure, and an inner wall surface of the battery container (5) are set so as to be capable of preventing the bolt (29) and the nut (128B) from detaching. An electrical insulating material (30) which prevents a wall surface section of the inner wall surface of the battery container (5) from making contact with the head part (29a) of the bolt (29) or the nut (128B) is fixed to the wall surface section which faces at least one of either the bolt head part (29a) or the nut (128B) with the gap therebetween, or is fixed to at least one of either the bolt head part (29a) or the nut (128B) which faces the wall surface section in question.</p> |
