Abstract
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.
