Combination weighing apparatus

A combination weighing apparatus comprising:

• a plurality of hoppers including a first hopper that discharges product retained therein, each of the plural hoppers having a discharge unit;
• a first drive unit that has a first heat emitting portion and drives the discharge unit;
• and
• a load cell that is secured to the first hopper and is for weighing the product retained in the first hopper,
• the load cell having
• a strain element having a first end portion secured to the first hopper, a second end portion that is an end portion on the opposite side of the first end portion, a first thin portion and a second thin portion disposed between the first end portion and the second end portion, and a first central portion disposed between the first thin portion and the second thin portion,
• a first strain gauge attached to the first thin portion,
• a second strain gauge attached to the second thin portion, and
• an electrical circuit that includes a first temperature-sensitive resistor and converts a change in the resistance of the first strain gauge and the second strain gauge to a voltage,
• the first central portion has a first surface that opposes the first heat emitting portion of the first drive unit and a second surface that does not oppose the first heat emitting portion of the first drive unit, and
• the first temperature-sensitive resistor is secured to the second surface of the first central portion.
