PROBLEM TO BE SOLVED: To provide a lamp diagnosis device capable of preventing other detection devices from making wrong judgments by minute current. SOLUTION: In a lamp diagnosis device provided with a N-P-N type transistor 15 supplying minute current to a stop lamp 1 and a computer 10 diagnosing the stop lamp 1 based on voltage applied to the stop lamp 1, the N-P-N transistor 15 intermittently supplies the minute current. Consequently, this lamp diagnosis device prevents other detection devices from making wrong judgments by the minute current by intermittently supplying the minute current to the stop lamp 1.
