A maleimide resin according to the present invention is formed by reacting a tetracarboxylic acid dianhydride (a1), an amine (a2), and maleic anhydride (a3), the amine (a2) including a dimer diamine and a secondary amine that is not a dimer diamine, and at least one of the tetracarboxylic acid dianhydride (a1) and the amine (a2) including a compound that has a fluorene skeleton. Une résine de maléimide selon la présente invention est formée par réaction d'un dianhydride d'acide tétracarboxylique (a1), d'une amine (a2) et d'anhydride maléique (a3), l'amine (a2) comprenant une diamine dimère et une amine secondaire qui n'est pas une diamine dimère, et le dianhydride d'acide tétracarboxylique (a1) et/ou l'amine (a2) comprenant un composé qui a un squelette de fluorène. テトラカルボン酸二無水物（ａ１）、アミン（ａ２）及び無水マレイン酸（ａ３）を反応させてなるマレイミド樹脂であって、アミン（ａ２）が、ダイマージアミンと、ダイマージアミン以外の第２のアミンとを含み、テトラカルボン酸二無水物（ａ１）及びアミン（ａ２）の少なくとも一方が、フルオレン骨格を有する化合物を含む、マレイミド樹脂。
