<p>A heat-resistant resin composition comprised of a mixture prepared by kneading a polybutylene terephthalate resin together with a component different from said polybutylene terephthalate resin, wherein a beta relaxation peak of said heat-resistant resin composition on the tan delta curve determined by the dynamic viscoelasticity measurement defined in Japanese Industrial Standard K 7244-4 appears at a temperature lower than a temperature at which a beta relaxation peak of a composition composed singly of a polybutylene terephthalate appears; and said another component is dispersed in said polybutylene terephthalate resin phase in a form of particles having sizes of 1 mum or smaller.</p> |
