PROBLEM TO BE SOLVED: To provide a resin molding technique that can improve productivity, while maintaining a good degassing degree.SOLUTION: An element 32 is a perforated pipe provided with a large number of fine holes 44 that pass air to a wall 43 but do not pass the liquefied resin. So-called a pipe made of hollow fiber membranes is optimal. When the liquefied resin containing air is made to flow as shown in an arrow (1), a portion of air passes through the wall 43 as shown in arrows (2) and (2) and is made to flow out to the outside of the element 32. The outside of the element 32 is in a vacuum state, and thereby the outflow of air is promoted. As a result, the liquefied resin with lowered air concentration is made to flow out from the element 32 as shown in an arrow (3). A moving distance of air is short, so that degassing is enabled in a short time and the productivity can be improved while maintaining a good degassing degree. |
