PROBLEM TO BE SOLVED: To provide a coaxial connection member capable of matching an antenna with a radio circuit securely, and an antenna power feeding structure capable of increasing SAR(specific absorption rate) by the use of the coaxial connection member. SOLUTION: A coaxial connection member 20 is composed by installing a cylindrical metal member 28 in the outside periphery around the axis of a spring connector 24 having a plunger 22 at its one end in a coaxial form through an insulating material 26, electrically connecting a signal terminal 34 formed at the other end of the spring connector 24 to a signal line 42 formed on a board 40, and electrically connecting earthing terminals 36 formed on the cylindrical metal member 28 to an earthing pattern 44 formed on the board 40. Then, an antenna power feeding structure is composed by elastically abutting the plunger 22 of the spring connector 24 of the coaxial connection member 20 on a power feeding fitting to which the base end of an antenna is electrically connected and which is installed in a radio device body 10, and electrically connecting the base end of the antenna to the signal line 42 of the board 40. |
