PROBLEM TO BE SOLVED: To provide a power supply device capable of improving connection reliability in a simple structure, restraining cost from rising, and miniaturizing. SOLUTION: The power supply device 1 has a battery collected body 2, a plurality of constrained bands 20, bar buses 9 and 10, and a connection member 28. The battery collected body 2 has a plurality of batteries 4. The batteries 4 are lined up along one direction H on condition that a positive electrode 6 and negative electrode 7 are provided and the positive electrode 6 and negative electrode 7 are alternately lined up in an inverse state. A plurality of batteries 4 are connected in series by connecting the mutually adjacent positive electrode 6 and negative electrode 7 with the bar buses 9 and 10. The plurality of constrained bands 20 fix the plurality of batteries 4 lined up along one direction H by bundling the plurality of batteries 4. The connection member 28 connects the negative electrode 7 of one battery 4a with one constrained band 20a so that connecting a first firmly fixing section and the negative electrode 7 of one battery 4a located on an end of one direction H where the plurality of batteries 4 are lined up are connected with each other and a second firmly fixing section and one constrained band 20a are connected with each other.
