Abstract: An electronic device includes an electronic component and a fixing structure. The electronic component includes a fixing portion, and a fixing hole is formed on the fixing portion. The fixing structure is for fixing the electronic component on a base plate. The fixing structure includes a main body, a fastening portion, a fixing pillar and an engaging component. A supporting plane is formed on an end of the main body. The fastening portion is connected to the other end of the main body and for fastening the main body on the base plate. The fixing pillar is disposed on the supporting plane. The fixing pillar is inserted into the fixing hole for constraining the electronic component. The engaging component is connected to a side of the main body, and the engaging component presses the electronic component so as to engage the electronic component on the supporting plane.
