Abstract:
1. A resin article comprising a plurality of parts including resin portions, the plurality of parts being bonded together through the resin portions, wherein the resin portions are bonded to each other by a method for bonding a first resin and a second resin, the method comprising the steps of: (I) irradiating a space containing oxygen molecules with vacuum ultraviolet light having a wavelength of 175 nm or smaller, the space being adjacent to a first surface of the first resin and a second surface of the second resin; and (II) after the irradiating, placing the first surface and the second surface in contact with each other, and increasing a temperature such that the first resin and the second resin are bonded to each other via the first and second surfaces serving as bonding surfaces, wherein the bonded resin portions are configured to become separable from each other by applying at least one liquid selected from water and alcohol at a temperature of 40° C. or higher, or by applying the liquid at a temperature lower than 40° C. in combination with ultrasonic vibrations.
