PROBLEM TO BE SOLVED: To reduce the weight of a waveform observing apparatus while securing its rigidity, and to easily cope with even a change in the number of required channels. SOLUTION: The waveform observing apparatus includes terminal blocks 25 for receiving wiring conductors from measuring instruments, measuring modules 230 for converting measurement signals received from the measuring instruments through the terminal blocks 25 into digital signals, and an in-body substrate 201 to which the measuring modules 230 are connected with connectors, and the apparatus stores measurement data in a memory and performs the waveform display of the data. The body frame 205 of the waveform observing apparatus is formed of a plastic molded frame. Moreover, this plastic molded frame has at least one pair of walls stretching while being mutually opposed to form a module insertion space for receiving a plurality of measuring modules 230. The measuring modules 230 and the terminal blocks 25 are connected with connectors, and longitudinal both ends of the terminal blocks 25 are fixed to one pair of walls detachably.
