PROBLEM TO BE SOLVED: To provide a gas exhaust pipe which inhibits dimensional changes of an area between cells and a gas exhaust pipe thereby preventing gas leakage and enables easy manufacturing and attachment.SOLUTION: A gas exhaust pipe 7 is attached to a battery pack 1 where substantially planar electric cells 2, 2 are disposed in a lamination manner and exhausts a gas occurring from the cells. The gas exhaust pipe 7 includes: a pipe body 71 made of a synthetic resin; a metal plate 73; and seal bodies 711. In the pipe body 71, through holes, which correspond to gas exhaust ports 21, 21 of the electric cells, are consecutively provided. The seal bodies 711 are provided on a pipe body outer peripheral surface so as to enclose the respective through holes. The metal plate 73 is formed so as to have a length corresponding to an entire length of the pipe body. Through holes, which respectively correspond to the through holes consecutively provided in the pipe body, are consecutively provided in the metal plate. The metal plate 73 is provided being inserted into the pipe body 71. The metal plate 73 is attached to the battery pack 1 thereby causing the seal bodies 711 to be held between the metal plate 73 and the electric cells 2. |
