Synthetic resin molded article and method for producing the same

A method for producing a synthetic resin molded article by covering a primary molded article, which has an electric element part and a primary molded part, with a synthetic resin, the electric element part being a semiconductor substrate extending in a distal direction from a proximal portion to a distal end portion, the primary molded part partly covering the electric element part, the method comprising:

• preparing the primary molded article having the primary molded part that includes an element covering portion and a body portion, wherein the element covering portion has a distal end surface and a first side surface, and is configured to cover the proximal portion of the electric element portion and to expose the distal end portion of the electric element portion from the distal end surface, the distal end surface exposing in the distal direction, the first side surface extending from an outer edge of the distal end surface in a proximal direction opposite to the distal direction, and the body portion has an intermediate surface and a second side surface, and is integrally connected to the element covering portion on a side of the element covering portion in the proximal direction, the intermediate surface exposing in the distal direction and extending in a direction intersecting with the proximal direction from an end of the first side surface, the end of the first side surface being adjacent to the proximal portion than the distal end portion, the second side surface extending from an outer edge of the intermediate surface in the proximal direction;
• setting the primary molded article to a mold for secondary molding that has an insertion hole for receiving the element covering portion and a molded article contact surface connecting to an opening portion of the insertion hole such that the intermediate surface is in contact with the molded article contact surface;
• and
• performing a secondary molding to cover a periphery of a region of the body portion further from the intermediate surface in the proximal direction with the synthetic resin, inside of the mold for the secondary molding.
