Abstract
A polyimide resin composition includes a polyimide resin (A) including a repeating structural units of formulas (1) and (2). The content ratio of the repeating structural unit of the formula (1) with respect to the total of the repeating structural units of the formulas (1) and (2) is 20 to 70 mol %. The polyimide resin composition further includes a fatty acid metal salt (B) including a fatty acid having 12 to 36 carbon atoms and optionally having a hydroxy group and at least one of an alkali metal, an alkaline earth metal, and a transition metal: wherein Rrepresents a divalent group having 6 to 22 carbon atoms containing at least one alicyclic hydrocarbon structure; Rrepresents a divalent chain aliphatic group having 5 to 16 carbon atoms; and Xand Xeach independently represent a tetravalent group having 6 to 22 carbon atoms containing at least one aromatic ring.
