  • an electronic device 1B according to the third embodiment is different from the electronic device 1A according to the second embodiment in that members 40B, tube fixing members 612B, 622B is different. Only different parts will be specifically described below.
  • a concave portion 4310 is provided on the tip surface of the fourth portion 431 of the member 40B.
  • a concave portion 4320 is provided on the distal end surface of the fifth portion 432 of the member 40B.
  • the tube fixing member 612B has a protrusion 6122 on the tip surface of the projection 6121.
  • the tube fixing member 622B has a protrusion 6222 on the tip surface of the projection 6221 .
  • the terminal base 135 is connected to the terminal fixing member 30, the nozzle 1321 is connected to the tube 611, and the nozzle 1322 is connected to the tube 621.
  • the convex portion 6122 and the concave portion 4310 are inserted into each other, and the convex portion 6222 is connected to the tube 621.
  • the pump 10 is stably fixed in the recess 200 by the fitted state of the recess 4320 and the recess 4320 .
  • the electronic device described above can be applied to, for example, an atomization device.
  • the atomization device atomizes a liquid with a gas having a predetermined flow rate and a predetermined pressure.
  • the pump 10 described above can generate a gas having a predetermined flow rate and a predetermined pressure. Therefore, it is useful to apply the atomization device as an electronic device.
  • the loss of gas transport in the pump 10 can be reduced. Therefore, an efficient atomization device can be realized.
  • the terminals for supplying drive signals must be installed at locations different from the two nozzles, and it is not easy to attach the pump 10 to the atomization device. I didn't. However, by applying the configuration of the electronic device described above to the atomization device, the pump 10 can be easily attached to the atomization device.
  • the electronic device is not limited to the atomization device, and any device that achieves a predetermined function using flowing gas can achieve the above effects by applying the above configuration.
