    • PROBLEM TO BE SOLVED: To provide a delay measurement method and radio base station device which measure, in simple configuration, delay of signals between a radio equipment control section and a radio equipment section. SOLUTION: A test jig is connected to the radio equipment control section, the radio equipment control section detects a head pattern of a master signal frame. supplies a detection signal to the test jig, sets a specific control signal indicating a head position of the master signal frame to a control signal of a radio signal frame to be converted from the master signal frame, and supplies the set specific control signal to the radio equipment section. The radio equipment control section inserts the head pattern into the master signal frame to be converted from the radio signal frame returned by the radio equipment section synchronously with the specific control signal of the radio signal frame, and supplies the master signal frame having the head pattern inserted therein to the test jig and the test jig measures a first time from the supply of the master signal frame from a master signal processing section to the radio equipment control section to the supply of the detection signal and a second time from the supply of the detection signal to the acquisition of the head pattern synchronized with the specific control signal of the main signal frame, thereby measuring a delay time between the radio equipment control section and the radio equipment section.
