Flame-retardant polyimide shaping material and shaped body

A flame-retardant polyimide molding material, comprising:

• a semi-aromatic polyimide resin (A);
• and
• 15 to 80 mass % of component (B2) which is at least one selected from the group consisting of a mixture of graphite and carbon fiber having a mass b1824ratio of 80:20 to 20:80, and a mixture of graphite, a fluorine resin, and carbon fiber where a content of two of the graphite, the fluorine resin, and the carbon fiber is each 30 mass % or more and a content of a third of the graphite, the fluorine resin, and the carbon fiber is 40 mass % or less, each based on a total mass of the mixture,
• wherein the semi-aromatic polyimide resin (A) is a polyimide resin (A1) comprising
• a repeating structural unit of formula (1) and
• a repeating structural unit of formula (2),
• where R1 is a divalent aliphatic group having from 6 to 22 carbon atoms comprising at least one alicyclic hydrocarbon structure,
• R2 is a divalent chain aliphatic group having from 5 to 16 carbon atoms,
• X1 and X2 are each independently a tetravalent aromatic group having from 6 to 22 carbon atoms, and the polyimide resin (A1) includes 20-70 mol % of the repeating structural unit of the formula (1) with respect to a total of the repeating structural unit of the formula (1) and the repeating structural unit of the formula (2).
