- 摘要：
To provide a root tip position detector capable of accurately detecting a root tip position.
SOLUTION: In the root tip position detector 10, a voltage application means 4 applies a first measuring voltage by a first frequency and a second measuring voltage by a second frequency different from the first frequency and a current component separation means 5 separates a first imaginary part from a first detection current based ON the application of the first measuring voltage and a second imaginary part from a second detection current based ON the application of the second measuring voltage. Then and a position detection means 6 detects the position of the root tip 1b by comparing the first imaginary part and the second imaginary part. The position detection means 6 determines that a measuring electrode 2 has reached the root tip 1b when the first imaginary part and the second imaginary part match and for instance.
