PROBLEM TO BE SOLVED: To solve the problem that a circuit is selected by a jumper member on a conventional board having a plurality of circuits for performing a function, the connecting state of the jumper member can be normally confirmed with naked eyes, the connection of the member is conducted by a machine or a by hand, and hence the connecting state of the member is, for example, changed by the third party except a manufacturer so that a way of using a product not intended by the manufacturer is executed or the like. SOLUTION: A terminal 40 is connected to a circuit A or the above-mentioned circuit B via a chip-like fuse connector 30. However, at the stage of providing the connector 30 on a board, the terminal 40 is connected to the circuit A and the circuit B via fuses 31a, 31b. Accordingly, only one of the above circuits is connected to the terminal 40 by melting either one of the fuses 31a and 31b.
