A method for producing a welded resin material and the welded resin material are provided to prevent molten resin from excluding and polluting environments by housing the molten resin in a closed space. A method for producing a welded resin material includes the steps of: superimposing a resin member(2) having transmissivity to laser beam and a resin member(3) having absorptivity to laser beam to form a contact part(21) where the resin members are in contact with each other; forming a closed space(6) adjacent to the contact part and faces one end of the contact part; and radiating the laser beam from the resin member having transmissivity while pressing the resin members to each other through the contact part, so as to heat the contact part to melt a resin at the contact part, housing a resin(7) excluded from the contact part through melting in the closed space, and solidifying the resin melted at the contact part to weld the resin members. |
