ABSTRACT:
A liquid detector includes: a case in which a flow channel is exposed from an opening; a sensor base, disposed in the opening of the case to face the flow channel; a sensor chip, mounted on a surface opposite to a surface of the sensor base which faces the flow channel and including a piezoelectric element; a film, adapted to hold the sensor base in the opening and sealing the opening; a circuit board, disposed in such a manner as to face the sensor chip; a relay terminal, electrically connecting the sensor chip and the circuit board; and a support member, adapted to support the circuit board and the relay terminal and fixed to the case. The relay terminal includes: a base end portion, fixed to the support member; and first and second free end portions, separately extending into two branches from the base end portion, and a first contact connected to the circuit board is formed in the first free end portion, and a second contact connected to the sensor chip is formed in the second free end portion.
