Polyimide resin composition and molded body

A polyimide resin composition comprising a polyimide resin (A) and a polyether sulfone resin (B), wherein

• the polyimide resin (A) comprises a repeating structural unit represented by the following formula (1) and a repeating structural unit represented by the following formula (2),
• a content ratio of the repeating structural unit of the formula (1) with respect to the total of the repeating structural unit of the formula (1) and the repeating structural unit of the formula (2) is 20 to 70 mol %,
• a total content of the polyimide resin (A) and the polyether sulfone resin (B) in the polyimide resin composition is 70% by mass or more, based on a total mass of the polyimide resin composition,
• a mass ratio of the polyimide resin (A) to the polyether sulfone resin (B), [(A)/(B)], is 10/90 to 60/40:
• wherein R1 represents a divalent group having from 6 to 22 carbon atoms containing at least one alicyclic hydrocarbon structure;
• R2 represents a divalent chain aliphatic group having from 5 to 16 carbon atoms;
• and
• X1 and X2 each independently represent a tetravalent group having from 6 to 22 carbon atoms containing at least one aromatic ring,
• the polyether sulfone resin (B) is a resin having a structure represented by formula (I):
• wherein R represents an end group, and is Cl or OH and n represents an average number of repeating structural units, and is a number of two or more, and
• wherein a tensile fracture strain, using a 1A-type test piece specified in JIS K7161-2:
• 2014 obtained by molding the polyimide resin composition to form a molded article, the tensile fracture strain measured by carrying out a tensile test at a temperature of 23° C., a distance between grips of 50 mm, and a testing speed of 5 mm/min in accordance with JIS K7161-1:2014 and K7161-2:2014, is 50% or more.
