A fluid collecting section is provided beside a measuring section, and an inner space of the fluid collecting section communicates with an inner space of the measuring section. Therefore, when the inner space of the measuring section is collapsed by pressing a measuring surface, fluid can escape toward the fluid collecting section. Consequently, the increase in internal pressure of the inner space of the measuring section is limited, and the upward force applied to an upper substrate in the measuring section is reduced. As a result, measurement sensitivity increases.
