1. A product-sum operation device comprising:
a product operator including a plurality of product operation elements connected to a line, each of the product operation elements being a resistance change element having;
a write terminal;
a common terminal;
a read terminal; and
a fuse portion included in the common terminal or the read terminal, the fuse portion being configured to be disconnected when a malfunction which increases an output current from the resistance change element has occurred in the resistance change element; and
a sum operator connected to the line connected to the plurality of product operation elements, the sum operator including an output detector configured to detect a sum of outputs from the plurality of product operation elements.
