PROBLEM TO BE SOLVED: To provide an easily-producible resin welded body having high productivity, capable of achieving stable sealability and highly-accurate dimensional control, and to provide a method of producing the same.SOLUTION: A plane in parallel with an abutment surface where a junction 4 is formed is defined as X-Y plane, and a direction vertical to the X-Y plane is defined as the Z direction. A seal member 8 is held between the outer peripheral surface of a guide 5 provided on a lid body 2 and the inner peripheral surface of a rib 6 provided on a case 3, and pressed to a direction in parallel with the X-Y plane. Further, while pressurizing the upper side of a stopper 7 by an annular pressurizing tool 9, the inner peripheral side thereof is scanned with laser light 10, and thereby a locus of the laser light 10 is not blocked by the pressurizing tool 9. Consequently, the selection width of the material of the pressurizing tool 9 is widened, and an easily maintainable tool can be used, to thereby improve productivity. |
