Abstract: The present disclosure relates to a gas sensor that minimizes the effects of humidity. The present disclosure relates to a gas sensor that minimizes the effects of humidity. Provided, in the present disclosure, is a gas sensor comprising: a substrate; a unit sensing unit disposed on the substrate and including a wiring electrode, a heater electrode, and a gas sensing material; a protective cap having a side wall part formed on the substrate and surrounding the unit sensing unit and a cover part disposed above the unit sensing unit and including at least one hole; and a heater unit disposed between the unit sensing unit and the cover unit, wherein the heater unit generates heat together with the heater electrode so as to lower humidity around the unit sensing unit.
