Apparatus with gas detection function

Abstract

Provided is an apparatus with a gas detection function capable of detecting a detection target gas with high accuracy. An apparatus with a gas detection function comprises: a housing (10); a vibration source (20); and a gas measurement unit (40) located inside the housing and demarcated by a partition, wherein the vibration source is located outside the gas measurement unit, the gas measurement unit includes a detector (41) located on a substrate (30), and a gas detection space (42) provided with a hole (43) through which a gas passes, and a frequency f expressed by the following Formula (1): f = c 2 ⁢ π ⁢ S VL Formula ⁢ ( 1 ) is 500 Hz or more, where V is a volume of the gas detection space, S is a cross-sectional area of the hole, L is an effective length of the hole, and c is a sound speed.
