A synthetic resin molded article includes an electric element part extending in a distal direction and a primary molded part. The primary molded part has an element covering portion and a body portion. The element covering portion has a distal end surface exposed in the distal direction and a first side surface extending in a proximal direction opposite to the distal direction. The element covering portion covers a proximal portion of the electric element portion, and a distal end portion of the electric element portion projects from the distal end surface in the distal direction. The body portion has an intermediate surface exposed in the distal direction and a second side surface extending in the proximal direction. The body portion is disposed on a side of the element covering portion in the distal direction and is integrally connected to the element covering portion.

Synthetic resin molded article and method for producing the same

A part of the sealed surface of the thermosetting resin member is a non-roughened surface that is not subjected to a roughening treatment. The other part of the sealed surface is a roughened surface recessed from the non-roughened surface to form a step and more roughened than the non-roughened surface. The thermoplastic resin member includes an additive added thereto, and the additive contains a functional group. A functional group existing in the roughened surface and the functional group existing in the additive are chemically bonded together. The roughened surface has a closed-circular shape that is formed over an entire circumference of the sealed surface around an axis parallel to the first direction. The three or more roughened surfaces each having a closed-circular shape on the sealed surface are arranged along the first direction with the non-roughened surface interposed as a distance between each adjacent two of the roughened surfaces.
