Provided is a polyester resin having exceptional adhesion and exceptional crushability. One embodiment of this polyester resin includes a structural unit A derived from a carboxylic acid of a ring structure having five or more carboxyl groups, and a structural unit derived from a dicarboxylic acid, wherein the structural unit A content is 0.01-45 molar parts per 100 molar parts of the structural unit derived from a dicarboxylic acid. L'invention concerne une résine de polyester ayant une adhérence exceptionnelle et une aptitude au broyage exceptionnelle. Un mode de réalisation de cette résine de polyester comprend un motif structural A dérivé d'un acide carboxylique d'une structure cyclique ayant au moins cinq groupes carboxyle, et un motif structural dérivé d'un acide dicarboxylique, la teneur en motif structural A allant de 0,01 à 45 parties molaires pour 100 parties molaires du motif structural dérivé d'un acide dicarboxylique. 優れた密着性及び優れた粉砕性を有するポリエステル樹脂を提供する。本発明のポリエステル樹脂の一態様は、カルボキシル基を５個以上有する環構造のカルボン酸由来の構成単位Ａと、ジカルボン酸由来の構成単位とを含むポリエステル樹脂であって、前記ジカルボン酸由来の構成単位１００モル部に対する前記構成単位Ａの含有率が０．０１モル部以上４５モル部以下である。
