PROBLEM TO BE SOLVED: To reduce the attenuation of a signal obtained during transmission, and further to accurately measure the electric characteristics of an object for testing with low signal attenuation. SOLUTION: A branch type probe is used for contact with an object for testing to detect the electric characteristics. The probe has: a contact head used for the contact with the object for testing; a first needle body; and a second needle body. The first needle body is connected to a contact head, sends a test signal to the object for testing, and executes detection. The second needle body is also connected to the contact head, sends a reaction signal generated by the object for testing according to the test signal, and obtains the electric characteristics of the object for testing.
