PROBLEM TO BE SOLVED: To reduce the thickness of an instrument body and to improve operability in a state where a test lead is installed.SOLUTION: An outer shape of an instrument body 4 is formed like a box, and on a rear surface 4b out of a plurality of surfaces constituting an exterior surface of the instrument body 4, linear grooves 41 reaching a top surface 4c being in contact with the rear surface 4b are formed in a Y direction orthogonal to a thickness direction of the instrument body 4 so as to have a length longer than that of connectors 13, and cover parts 44 are arranged which cover openings of the linear grooves 41 over a length equal to the length from deep walls 42 of the linear grooves 41 to front end parts of the connectors 13, and a bottomed holding cylinder part 46 to which front end parts of the connectors 13 of test leads 2 and 3 are to be inserted is formed of the cover parts 44, the deep walls 42, and portions facing the cover parts 44, of the rear surface 4b. |
