Abstract
A method of making a contact probe including a step of making a first printed wiring board having a signal electrode and a ground electrode used as a contact part of the contact probe with respect to a measuring object, in which the signal electrode and ground electrode are formed of a metal wiring pattern, and making a second printed wiring board with a coaxial line structure having a shield electrode which encloses a signal line and the surroundings of the signal line through an insulating layer. The signal electrode of the first printed wiring board and the signal line of the second printed wiring board are electrically connected together, and the ground electrode of the first printed wiring board and the shield electrode of the second printed wiring board are electrically connected together.
