Load detection sensor and load detection sensor unit

A load detection sensor comprising:

• a first electrode sheet which includes at least one first electrode and a first contact point;
• a second electrode sheet which includes a second electrode facing the first electrode and a second contact point facing the first contact point and electrically connected to the second electrode;
• a spacer which is disposed between the first electrode sheet and the second electrode sheet and includes at least an opening formed between the first electrode and the second electrode and between the first contact point and the second contact point;
• one terminal which is electrically connected to the first electrode;
• and
• the other terminal which is electrically connected to the first contact point,
• wherein a switch is formed by the first electrode and the second electrode and a connection maintaining portion in which an electrical connection is maintained even when an external pressure is not applied thereto is formed by the first contact point and the second contact point, and
• wherein odd series of the switches electrically connected in series between the one terminal and the other terminal are set.
