Comparative Example 11 A resin composition was prepared with the composition ratio shown in Table 5, that is, the glass fiber content was less than 8% by weight, and its physical properties were evaluated in the same manner as in Example 11. As a result, heat resistance, It was found that the rigidity, impact resistance, and amount of warpage were poor, and the desired physical properties could not be obtained, making it undesirable.
