Abstract
It is an object to provide a flow rate sensor device having improved sensor responsiveness compared with the prior art. The present invention is a flow rate sensor device including a sensor element that detects a flow rate, wherein a sensor unit on which the sensor element is mounted and a drive substrate including a drive control circuit are connected through a connection portion narrower than a width of the drive substrate. Thus, a heat source in the drive substrate and a heat source in the sensor unit can be separated by the connection portion that is thin in width, and the thermal influence from the drive substrate to the sensor unit can be suppressed. Therefore, good sensor responsiveness can be maintained.
