A physical quantity sensor is produced using a lead frame having at least one stage for mounting a physical quantity sensor chip and a frame having leads, wherein the physical quantity sensor chip is inclined with respect to the frame. A bonding device performs wire bonding so as to electrically connect the physical quantity sensor chip and leads, which are respectively located perpendicular to a capillary for discharging wires. The bonding device includes a wedge tool having a first planar surface for holding one ends of wires with leads and a second planar surface for holding the other ends of wires with the physical quantity sensor chip. The lead frame includes interconnection leads, having shape memory alloys, for interconnecting the stage and frame together. The physical quantity sensor chip can be mounted on the stage via an inclination member having a wedge shape. |
