<P>PROBLEM TO BE SOLVED: To provide a composite material for injection molding which is excellent in flowability during injection molding and to provide an injection-molded product obtained by using the same. Ž<P>SOLUTION: The composite material is obtained by melting and kneading a polybutylene terephthalate having no sulfonic acid group (component A), a fiber-like inorganic filler (component B), and an organized layered silicate (component C), wherein the component C is in a dispersed state while allowing layer separation. In the composite material, an alkali metal salt (component D) of a 16-32C monocarboxylic acid is mixed as an aggregation prevention agent for preventing the aggregation of the component C in a dispersed state when the composite material is again heated and melted. The composite material contains, by mass, 60-75% component A, 15-35% component B, 1-10% component C and 0.5-5% component D when the total amounts of the components A, B, C and D are 100%.
