To provide a terminal connection conversion tool for an LSI evaluation board, and an LSI evaluation method capable of evaluating an LSI without reproducing an LSI evaluation board even when terminal arrangement of the LSI is changed.

The terminal connection conversion tool for an LSI evaluation board and the LSI evaluation method capable of evaluating the LSI without reproducing the LSI evaluation board even when the terminal arrangement of the LSI is changed can be provided by using the conversion tool 8 which controls connection and non-connection of a terminal for the LSI and a terminal 5 of the LSI evaluation board, which are previously corresponded, by a slide switch 10, connecting a terminal window 11 by a lead wire, and optionally setting correspondence of the terminal of the LSI and the terminal 5 of the LSI evaluation board.
