A piezoelectric element unit comprises an element body having an active part and an inactive part; and a first resin part bonding one end surface in the laminating direction of the element body to a mounting surface of a joint member placed to face the one end surface. The first resin part covers the mounting surface up to an outer side surface of the element body corresponding to an interface between the active part and the inactive part, a second resin part covers an outer surface of the first resin part covering the outer side surface of the element body at a position corresponding to the interface between the active part and the inactive part, and the second resin part also integrally covers the outer side surface of the element body corresponding to the active part.

The present invention relates to a method for detecting substances specifically inhibiting a type III secretion mechanism and functions of the type III secretory proteins, within short time and large amounts thereof, without depending upon animal infectious experiments. Namely it relates to the method for detection of a type III secretory mechanism inhibitor comprising mixing a bacterium having the type III secretory mechanism and an erythrocyte suspension, adding the type III secretory mechanism inhibitor thereto, and detecting changes in the thus formed hemolytic activity. The method for detecting substances can be treated large amount of samples within short time by exhibiting the substances inhibiting the type III secretion mechanism or the functions of the type III secretory proteins as numerical index of the hemolytic activity of erythrocytes. Consequently, the present invention is useful for development of drugs.
