An injection device including a housing, a control module, a heating module and an injection module is provided. The control module is disposed to the housing. The heating module includes at least one heat conducting element and at least one heater. The at least one heat conducting element is disposed to the housing and adapted to assemble a syringe. The at least one heater connected to the at least one heat conducting element and electrically connected to the control module. The injection module is disposed to the housing and electrically connected to the control module. The control module is adapted to receive an external operation signal and send a control signal to control the at least one heater to heat the at least one heat conducting element, so that the at least one heat conducting element heats the syringe to a target temperature, and the injection module controls the injection of the syringe at an injection speed and an injection amount.一種注射裝置，包括一殼體、一控制模組、一加熱模組及一注射模組。控制模組設置於殼體。加熱模組包括至少一導熱件及至少一加熱器。導熱件設置於殼體且適於裝設一注射器。加熱器連接導熱件且電性連接控制模組。注射模組設置於殼體且電性連接控制模組。控制模組適於接收外部的操作訊號進而發出控制訊號，以控制加熱器加熱導熱件，進而使導熱件加熱注射器至一目標溫度，及控制注射模組推動注射器以一注射速度及一注射量進行注射。
