1. An electrode substrate having electrodes for measuring an electrical resistance of biological cells or tissues, comprising:
a substrate having a base section, a first extension part extending from said base section, and a second extension part extending from said base section;
a plurality of connection terminals provided on a surface of said base section;
a first working electrode and a second working electrode each connected to one of said connection terminals, said first and second working electrodes being wired on a surface of said substrate; and
an engagement surface provided on said substrate and facing toward said connection terminals in a position closer to said first extension part than said connection terminals,
said first working electrode being wired from said base section to said first extension part,
said second working electrode being wired from said base section to said second extension part,
said first extension part extending in a first direction,
said engagement surface protruding in a second direction orthogonal to said first direction away from said second extension part and beyond said first extension part, and
said engagement surface being integrally formed with said base section.
