PROBLEM TO BE SOLVED: To provide a resin molding capable of inhibiting both a rigidity attenuation and a hermeticity deterioration; and a method for manufacturing the same.SOLUTION: In a resin molding including: a cylindrical unit (10) possessing a bottom unit (11) and a cyclic wall unit (12) formed on the fringe of the bottom unit; a columnar unit (30) configured within an inner space surrounded by the wall unit of the cylindrical unit; and a resin unit (50) filled into the gap between the columnar unit and the cylindrical unit, an air release hole (13) for inhibiting, on an occasion where the columnar unit has been inserted into the inner space of the cylindrical unit and where a molten resin has been filled into the gap between the cylindrical unit and the columnar unit, the lingering of air within the space between the cylindrical unit and the columnar unit is formed on the bottom unit of the cylindrical unit, whereas a cyclic protrusion unit (14) scheduled to be melted by a shear heat generated as a result of the fluidization of the molten resin is formed on the periphery of the air release hole on the bottom unit. |
