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 (1) including a sensor element (3, 4) that detects a flow rate, wherein a sensor unit (10) on which the sensor element (3, 4) is mounted and a drive substrate (11) including a drive control circuit are connected through a connection portion (12) narrower than a width of the drive substrate (11). Thus, a heat source in the drive substrate (11) and a heat source in the sensor unit (10) can be separated by the connection portion (12) that is thin in width, and the thermal influence from the drive substrate (11) to the sensor unit (10) can be suppressed. Therefore, good sensor responsiveness can be maintained.

An object is to provide a flow sensor element is non-directional and has an excellent sensor sensitivity. A flow sensor element includes a base body having a spherical shape, and a temperature-sensitive film pattern that is disposed over the entirety of a surface of the base body, and changes in an electrical resistance value due to a change in temperature. It is preferable that the temperature-sensitive film pattern be formed by trimming a temperature-sensitive film that has been formed on the surface of the base body. In the flow sensor element, the temperature-sensitive film pattern can be disposed over the entirety of the surface of the base body having a spherical shape. This enables a constant sensor sensitivity to be obtained regardless of a direction of a fluid, and the accuracy of detection of a flow rate can be improved.
