The present invention provides a warp-knitted fabric and a medical material that can be simultaneously extended in all directions by causing thread made of a second bioabsorbable material to be absorbed in a living body over time and in which the degree of extension can be increased. The present invention provides a warp-knitted fabric 10 in which adjacent loop rows are linked, the warp-knitted fabric 10 including: a plurality of first loop rows including a first thread and composed of continuous loops extending in the warp direction; and one or two or more second loop rows disposed between the first loop rows and composed of continuous loops extending in the warp direction, wherein each second loop row is formed of one or two or more loops solely including a second thread and one or two or more loops including the first thread, which are arranged alternately, at least three first loop rows are linked together by the first thread, and the bioabsorption rate of the first thread is lower than the bioabsorption rate of the second thread.
