To provide an information transmission device for reducing a failure occurrence rate in a control section and a transmission section.SOLUTION: In a sensor node 10, a bottom plate 11a of a frame 11 is held between an internal space Sa where a control module 23 and a wireless module 24 are stored and a lower cover 15 which transmits heat input from the outer side to a heat receiving side substrate 31 of a Peltier unit 30. Then, the bottom plate 11a functions as a partition wall, so as to make it difficult to allow the heat input to the lower cover 15 to be transmitted to the internal space Sa. Consequently, in the sensor node 10, the control module 23 and the wireless module 24 are prevented from being exposed to high temperature even when attached to positions close to a high temperature heat generation source, since the heat input to the lower cover 15 is not easily transmitted to the internal space Sa. Thus, problems such as performance deterioration or failure occurrence due to exposure of electronic components of the control module 23 and the wireless module 24 to high temperature are suppressed, so that the failure occurrence rate can be reduced.SELECTED DRAWING: Figure 2
