PROBLEM TO BE SOLVED: To provide an imaging apparatus for resin welded part for imaging a three dimensional geometry of a weld surface of a transparent resin and an opaque resin welded by a laser beam. SOLUTION: The imaging apparatus comprises: an infrared ray source 17 for irradiating a welded part 3 with an irradiation ray with a wavelength passing through a transparent resin 1 but not through an opaque resin 2; an infrared ray camera 10 arranged over the welded part 3; a pair of relay mirrors 25, 26 placed both the sides of the welded part 3 for imaging the surface of the half region of the bump part of the welded part 3 from aslant upsides respectively and reflecting toward opposite directions to each other; a pair of central relay mirrors 20, 21 for reflecting the image to the half region of both the side of the objective lens 11 while facing relay mirrors 25, 26 in front of an infrared camera 10; a band pass filter 12 arranged between the relay mirrors and the infrared camera 10; and an image display device 30 for displaying the image signal of the infrared camera 10 on the screen 31, which is imaged by the irradiation light.
