DEVICE FOR DETECTING A SUBSTANCE IN A LIQUID AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2011/046059

A1

Disclosed is a device for detecting a substance in a liquid, said device being capable of precise, stable detection of a substance. Also disclosed is a method for manufacturing said device. The device (1) for detecting a substance in a liquid is provided with: a substrate (30) in which openings (30a, 30b) are formed; an elastic surface-wave element (10) that has a piezoelectric substrate (11), has IDT electrodes (12, 15) that constitute sensing parts (18, 19), and is mounted on the substrate (30) such that the sensing parts (18, 19) face the openings (30a, 3b) in the substrate (30); and a resin layer (40) that is formed between the substrate (30) and the elastic surface-wave element (10) so as to surround the sensing parts (18, 19). The disclosed device for detecting a substance in a liquid is manufactured by: preparing a mounted structure (42) in which the elastic surface-wave element (10) is mounted on the substrate (30), at least the inside surfaces of the openings (30a, 30b) of which are hydrophobic; forming the resin layer (40) in the mounted structure (42); and hydrophilizing the surfaces of detection depressions (32, 33).
