Claims

[Scope of utility model registration request]

(1) A detector including a detection section having a detection element provided at the tip of the case, and a circuit section connected to the detection section and detecting an external state based on a change in the detection element, By bending the lead wire connecting the detection part and the circuit part,
A detector characterized in that a connecting tip on the circuit section side is connected toward the detection section.

(2) The detection section has a coil embedded in the annular groove of the core as a detection element, and the circuit section has an oscillation section that uses the coil as a resonant circuit, and detects the presence or absence of an object near the coil. The detector according to claim 1 of the utility model registration, characterized in that the detector is for detecting.

(3) The detector according to claim 1 or 2, which is a registered utility model, characterized in that an elastic resin covering the connection portion of the lead wire on the circuit side is coated and cured.
