ABSTRACT:
The present invention provides a method for joining liquid-crystalline polyester resin composition parts, characterized in that the melting point of the liquid crystalline polyester resin measured by differential scanning calorimeter is 190-250° C. and that the parts are jointed by means of welding. By using the method of the present invention, jointed articles with sufficient joint strength are provided with accuracy.
