ABSTRACT:
A high-voltage variable resistor includes a structure which makes it possible to achieve stable and reliable contact conduction between a connection terminal 7 and a terminal electrode 2a. The connection terminal 7 comprises a spring portion 7b. At the end of the spring terminal 7b there is provided a flat contact section 7d which is wider than the other portions thereof. A plurality of protrusions 7e, 7f are formed on this contact section 7d. The outer edge portion of a lead line connecting section 7a of the connection terminal 7, which is accommodated in and fixed to a connection terminal accommodating section 6, is held in a terminal holding groove 6a of the connection terminal holding section 6, and the protrusions 7e, 7f are held in contact with the terminal electrode 2a of an insulating substrate 2 and pressed against the insulating substrate 2. A core wire 8a of a lead line 8, which is inserted into a lead line holding cylinder 1b, is held by holding members 7c of the connection terminal 7 and connected to the connection terminal 7 thereby.
