The present invention relates to a vehicular gas sensing device having multi-sensor to prevent moisture outside a main body from flowing into a gas detection sensor. The present invention prevents moisture inside the main body from flowing into the gas detection sensor by filtering out small foreign substances or moisture through a first filter and subsequently filtering out moisture which has not been filtered out through the first filter through a second filter.
