Abstract
A temperature sensor including a temperature sensitive device which is disposed in a flow path through which fluid flows and whose electric characteristic changes as a function of temperature of the fluid in the flow path, signal lines connected at top end sides thereof to said temperature sensitive device through electrode wires and at base end sides thereof to lead wires for connection with an external circuit, a sheath member retaining the signal lines therein, and a holding member which holds an outer circumferential surface of said sheath member directly or indirectly through another member. The resonance (primary) frequency at a top end of the temperature sensor against acceleration in a radius direction of the temperature sensor is 480 Hz or less, thereby reducing the transmission of vibration to the top end of the temperature sensor to avoid the breakage of the temperature sensitive device and the disconnection of the electrode wires 502102 even when the temperature sensor resonates.
