<P>PROBLEM TO BE SOLVED: To provide a laminate battery capable of improving sealing performance. <P>SOLUTION: A laminate film 4 of a laminate battery has a seal portion 42 and a resin reservoir 416. The seal portion 42 includes resin 415. The resin reservoir 416 is disposed in contact with the end part of the resin 415 on a power generating element 20 side. The end part of the resin reservoir 416 on the power generating element 20 side includes a protrusion 4161 and dents 4162, 4163. The protrusion 4161 is projected in an arc-shape on the power generating element 20 side. The dent 4162 is disposed on one end of the protrusion 4161 to continue thereto in a thickness direction of the seal portion 42, and is dented in an arc-shape in a direction opposite to the projection direction of the protrusion 4161. The dent 4163 is disposed on the other end of the protrusion 4161 to continue thereto in the thickness direction of the seal portion 42, and is dented in an arc-shape in a direction opposite to the projection direction of the protrusion 4161. <P>COPYRIGHT: (C)2012,JPO&INPIT |
