Abstract:
1. A heat-resistant resin composition comprising: a polyarylene sulfide resin (A) having a non-Newtonian index of 1.3 to 0.9; and; an aromatic polyamide (B) having terephthalic acid amide as an essential structural unit, wherein the aromatic polyamide (B) comprises a terephthalate amide structure represented by following Structural Formula a: wherein R is an alkylene group having 2 to 12 carbon atoms, wherein a content of the terephthalate amide structure is 65% by mole or more with respect to a total acid amide structural unit constituting the aromatic polyamide (B); a ratio [(A)/(B)] of the polyarylene sulfide resin (A) to the aromatic polyamide (B) is 70/30 to 95/5 by mass; the aromatic polyamide (B) is particulately dispersed in the polyarylene sulfide resin (A) as a matrix, and an average diameter of particles of the aromatic polyamide (B) is in a range of 0.1 to 1.0 μm.
