To provide an inertial measurement device, an electronic apparatus, and a mobile body with excellent anti-vibration characteristics.SOLUTION: An inertial measurement device 1 includes: a sensor unit 10 which has an angular velocity sensor and an acceleration sensor; an elastic member 16 which has a first part 16a, a second part 16b opposite to the first part 16a, and a third part 16c connected to the second part 16b, and sandwiches the sensor unit 10 with the first part 16a and the second part 16b; a fixed part 12 in which the sensor unit 10 and the elastic member 16 are arranged and which is in contact with the second part 16b; and a fixing member 14 which fixes the sensor unit 10 and the elastic member 16 to the fixed part 12. The fixing member 14 penetrates the sensor unit 10 and the elastic member 16 to press and fix the elastic member 16. The third part 16c of the elastic member 16 is located between the sensor unit 10 and the fixing member 14.SELECTED DRAWING: Figure 4 【課題】防振特性に優れた慣性計測装置、電子機器、及び移動体を提供する。【解決手段】慣性計測装置１は、角速度センサー及び加速度センサーを有するセンサーユニット１０と、第１部分１６ａと、第１部分１６ａに対向する第２部分１６ｂと、第２部分１６ｂと連結する第３部分１６ｃと、を有し、第１部分１６ａと第２部分１６ｂとでセンサーユニット１０を挟む弾性部材１６と、センサーユニット１０と弾性部材１６とが配置され、第２部分１６ｂと接する固定部１２と、固定部１２にセンサーユニット１０と弾性部材１６とを固定する固定部材１４と、を備え、固定部材１４は、センサーユニット１０と弾性部材１６とを貫通し、弾性部材１６を押圧して固定し、弾性部材１６の第３部分１６ｃは、センサーユニット１０と固定部材１４との間に位置する。【選択図】図４
