PROBLEM TO BE SOLVED: To provide a power supply unit capable of suppressing a malfunction of electronic apparatus caused by static electricity conducted from a person who operates a service plug.SOLUTION: A service plug 3 includes: a first conductive part 34 that is connected in series to a battery pack 1 in a state of being connected to a current path 4; a second conductive part 31 that is operated when a connection state between the service plug 3 and the current path 4 is released and is isolated from the first conductive part 34. The second conductive part 31 is grounded by being electrically connected to a frame 6 that forms a reference potential point. |
