A feeding rod is configured to insert a shaft-shaped component having a circular flange and a shaft portion into a receiving hole. A central axis of the shaft portion is disposed in an inclined state with respect to a central axis of the receiving hole due to the inclined disposition of the feeding rod. A surface of the flange is in close contact with a tip surface of the feeding rod due to an attraction force of a magnet of the feeding rod. A positioning protrusion receives an outer peripheral portion of the flange and sets a relative position between the feeding rod and the shaft-shaped component. A most advanced stop position of the feeding rod is a position where a tip portion of the shaft portion has entered the receiving hole, and the attraction force of the magnet is configured to be eliminated at the stop position.

There is provided a component joining structure that includes: a resin component; a metal tip that is provided in the resin component by insert molding, and that includes protruding portions that protrude from the resin component; and a metal component that is spot welded to the protruding portions, and that is joined to the resin component by an adhesive agent that is provided in gaps formed, by the protruding portions, between the resin component and the metal component.

Provided are a three-dimensional shaped object production device and method capable of producing a predetermined three-dimensional shaped object by forming a ball at a leading end of a conductive wire through use of the conductive wire based on scanned data or designed data and aligning and stacking the balls. The three-dimensional shaped object production device includes: a plate (40), on which a three-dimensional shaped object is placeable; a ball forming section configured to form a ball (13) by applying high voltage between a leading end of a conductive wire (4) paid out from a leading end of a capillary (12) and a spark rod (19) and melting the leading end of the wire by discharge energy; a positioning device configured to position the plate and the ball forming section by moving the plate and the ball forming section relative to each other; and a bonding section configured to bond the ball formed at the leading end of the capillary to another ball (14) that has already been stacked on the plate, the forming of the ball by the ball forming section, the relative moving of the plate and the ball forming section by the positioning device, and the bonding of the ball formed at the leading end of the capillary to the another ball by the bonding section is repeated, to thereby produce a three-dimensional shaped object having a desired shape.
