A rubber composition capable of improving fuel economy, wet grip performance and wear resistance in a well-balanced manner, and a pneumatic tire using the rubber composition. A rubber component, silica, and a liquid resin having a softening point of -20 to 20 ° C., and 100% by mass of the rubber component is represented by a structural unit based on a conjugated diene and represented by the following formula (I): A conjugated diene polymer in which at least one end of the polymer is modified with a silicon compound having an amide group, a carboxylic acid ester group, a methacryloyl group, an acryloyl group, an oxydialkylene group or an alkylene oxide group It is related with the rubber composition whose content of is 5 mass% or more and whose content of the said silica with respect to 100 mass parts of said rubber components is 5-150 mass parts.
