According to the present invention, provided is a polyvinyl acetal resin capable of obtaining a ceramic green sheet that has sufficient mechanical strength, in which the dimensional change in the storage of ceramic green sheet is small, and the delamination hardly occurs in the delipidation. The present invention relates to a polyvinyl acetal resin that has a degree of polymerization of 200 or more to 6000 or less, a content percentage of vinylester unit of 0.01 to 30 mol%, a degree of acetalization of 55 to 83 mol%, and a structural unit represented by Chemical formula (1):
in a molecule. |
