PURPOSE:To improve the product yield by providing a resin well pot in the through-gate portion between the product cavities, thereby preventing a void from biting the product. CONSTITUTION:A resin well pot 15 is provided in a through-gate portion 11. With this, the air seized in the encapsulating resin becomes a void at the through-gate portion 11. However, since the apparent through-gate volume increases, the air is trapped in the resin well pot 15. |
