PROBLEM TO BE SOLVED: To provide an in-vehicle electric component testing device capable of testing a plurality of in-vehicle electric components in various combinations. SOLUTION: An operation pattern making part individually operates the respective electric components in the beginning by commanding an operation command signal output part 11 to successively and individually operate the plurality of electric components, and afterwards, simultaneously operates the plurality of electric components by commanding the operation command output 11 to operate the plurality of electric components combined at random, and gathers an operation state by a signal monitoring part 13 when individually operating the electric components. A data memory analyzing part 14 stores this state, and afterwards, a comparing part 16 compares the operation state when operating the plurality of electric components with the stored individually operating time operation state.
