An object of the present invention is to provide a sheet joined body having a high joint strength while limiting an amount of adhesive to be used. A method of producing a sheet joined body includes: abutting ends of sheet members against each other, coating an abutted part with a joining member containing a thermoplastic resin, and irradiating a part coated with the joining member, with laser light to join the sheet members with the joining member by welding, thereby joining the ends with each other to manufacture the sheet joined body. |
