A resin composition which is high in strength, rigidity, and heat resistance, has excellent toughness, and is excellent in weld strength retention, dimensional properties, surface appearance, and reworkability. It hence has a balanced combination of physical properties. The resin composition comprises a resin and apatite, and is characterized in that the apatite present in the resin composition has such a particle shape that the average diameter or average thickness (d) is 100 nm or small and the ratio of the average length (L) to the average diameter or average thickness (d), i.e., average aspect ratio (L/d), is 5 or higher. |
