A knitted fabric includes: a first knitted fabric region and a second knitted fabric region. The first region and the second region have different elongations from each other. The knitted fabric further includes buffer regions. The buffer regions are provided in at least one of the first region and the second region so as to be in contact with the first region and the second region. The buffer regions each have an elongation set so that, as the buffer region extends toward either one of the first region and the second region, the difference between the elongation of the buffer region and the elongation of the first region or the second region toward which the buffer region extends is reduced gradually. Between the first region and the second region, there is no boundary line that is substantially parallel to the course direction of the knitted fabric.
