Method of producing sealing structure of bipolar battery, method of manufacturing bipolar battery, sealing structure of bipolar battery, and bipolar battery

The present invention is intended to provide a method of producing a sealing structure of a bipolar battery capable of improving the sealing capability by means of solidifying the joint between a resin collector comprising a thermosetting resin before the setting reaction and a sealing layer, a method of producing the bipolar battery, and the sealing structure of the bipolar battery and the bipolar battery. The method of producing the sealing structure of the bipolar battery comprises s step of producing the sealing assembly 80 by joining the first sealing layer 81 consisting of thermosetting resin before the thermosetting reaction with the second sealing layer 82 consisting of the thermoplastic resin, and a step of producing the collector assembly 90 formed by sealing the contact area of the sealing assembly and the resin collector 60 by joining the sealing assembly with the thermosetting resin after the thermosetting reaction.
