PROBLEM TO BE SOLVED: To provide a sensor device capable of accurately detecting the temperature of gas as the detection target. ! SOLUTION: A sensor device 1 comprises: a main body 10 inside which a gas passage 13 extending in an upstream direction from a gas inflow end is formed; a pressure sensor 30 which is provided in the main body 10 in communication with the gas passage 13 and detects a pressure of gas in the gas passage 13; and a temperature sensor 20 having a sheath tube 21 inserted into the gas passage 13. The sheath tube 21 has a temperature-sensitive part for detecting a temperature of gas, and also has a fin member 51 on an outer peripheral surface near the temperature-sensitive part. The fin member 51 is provided with multiple fins 511 having a separation surface which is separated from the sheath tube 21 further as it goes from upstream direction toward downstream direction in the gas passage 13. !
