A method for joining thermoplastic resin molded products by pressing together joining surfaces of two molded products with electric resistance wire therebetween is provided, wherein the method comprising: a first step in which electric resistance wire 20 is sandwiched between the joining surfaces of two molded products which are to be joined, pressure is applied at a first predetermined pressure, and current of a predetermined value is applied for a predetermined time to the electric resistance wire, so that the resin around the electric resistance wire is melted by the thermal energy produced in the electric resistance wire while the surfaces of the two molded products that are to be joined are held at a predetermined interval; and a second step in which, following the conclusion of the first step, the current being applied to the electric resistance wire is stopped, and a second predetermined pressure is applied to attach the molten resin under pressure.
