    摘要： A prepreg containing a matrix resin containing: a polyetherimide resin (A) having a repeating unit represented by General Formula (A); and carbon fibers, in which the matrix resin satisfies Condition (1). Condition (1): A tensile elongation at break (T1) of a film, obtained by extrusion-molding the matrix resin into a film shape, in a TD direction, and a tensile elongation at break (T2) of the film in the TD direction after immersing of the film for 1,000 hours in a specific oil at 23°C are measured, and a tensile elongation retention rate obtained by Expression (1) is 15% or greater and 90% or less. Tensile Elongation Retention Rate = (Tensile Elongation at Break (T2)/Tensile Elongation at Break (T1) × 100 ... (1) (in Formula (a), m is a number of 5 to 1,500.)
