The invention relates to an automotive natural gas leakage alarm sensing probe. The automotive natural gas leakage alarm sensing probe comprises a shell, a bottom cover and a built-in circuit board. The surface of the shell is an arc-shaped face. A plurality of grooves are formed in the arc-shaped face in parallel. Gaps are formed in the side faces of the grooves to serve as vent holes. The built-in circuit board is arranged between the bottom cover and an inner cavity of the shell in a suspended mode. Meanwhile, wires are arranged on the built-in circuit board and led out of the space between the shell and the bottom cover. The automotive natural gas leakage alarm sensing probe is simple in structure and convenient to use; large-concentration high-speed gas flow can be prevented from directly impacting on sensing elements, and the service life of the sensing elements is prolonged; and the sampling stability of sensitive elements can be improved, and the automotive natural gas leakage alarm sensing probe is quite suitable for popularization and implementation.
