Pressure-bonding unit and pressure-bonding head unit

A pressure-bonding unit, where a pressure-bonding surface of a head is contacted with pressure to a predetermined portion of a second object temporarily fixed to a first object and where said second object is pressed to said first object so that said second object is bonded to the first object with pressure, comprising:

• a pressure-bonding head having said pressure-bonding surface;
• pressure-bonding head holding means for integrally fixing and holding said pressure-bonding head, the pressure-bonding head holding means being formed with a cutout from the side of a first direction side in parallel with said pressure-bonding surface and also being formed with an opening perpendicular both to said first direction and said pressure-bonding surface;
• first deformation means for deforming said pressure-bonding head holding means so that a cutout inlet of said cutout opens or closes by a desired amount;
• and
• second deformation means for deforming said pressure-bonding head holding means so that one opening end or the other opening end of said opening of said pressure-bonding head holding means is crushed in a direction parallel to said first direction by desired amount.
