Provided is a reductant container having: a tank main body that accommodates a reductant; a heating member disposed in the tank main body and configured to generate heat so as to increase a temperature of the reductant; a covering member covering the heating member and having an inflow portion, the inflow portion allowing some of the reductant accommodated in the tank main body to flow into the covering member; a reductant supply pipe through which the reductant in the covering member is supplied to the outside of the tank main body; and a temperature measuring unit having a temperature sensor disposed in the covering member to sense a temperature of the reductant in the covering member, the temperature measuring unit determining the temperature sensed by the temperature sensor, wherein the covering member has an upper wall covering the heating member from above, the upper wall having a lower surface that is inclined so as to be raised toward the temperature sensor.
