<p><P>PROBLEM TO BE SOLVED: To provide an electrode structure capable of carrying out easily temporary fixing of a bolt to a metal terminal, and a manufacturing method of a battery device. <P>SOLUTION: The electrode 21 is provided with a metal terminal 41 which extends from a battery module body, a bolt 31 which has an expansion part 35 to constitute a retaining section at the rear end and penetrates the metal terminal 41 upward, and an insulator 43 which insulates between the metal terminal 41 and a case of the battery module. The insulator 43 has a coming-off prevention part 45 which contacts at least the lower face of the expansion part 35 of the bolt 31 and prevents coming off of the bolt 31 from the metal terminal 41. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
