Abstract: Provided is a circular knitted fabric that has a good balance in elongation between a wale direction and a course direction, and also a knitted pattern. A circular knitted fabric having a 1×1 rib jacquard knitted structure as a basic structure, in which non-elastic fiber yarn and elastic fiber yarn are fed as a full set and are plate-knitted, knit-loops account for 10 to 90% of all structures, and at least any one of a tuck and a welt is included so that a knitted pattern is formed on a knitted fabric surface due to a difference between structures by location, elongation in each of a wale direction and a course direction is 100 to 280% under a load condition of 14.7 N/2.54 cm, and an elongation ratio, that is, (elongation in wale direction)/(elongation in course direction), is 0.5 to 2.0 under the load condition of 14.7 N/2.54 cm.
