PROBLEM TO BE SOLVED: To provide a radio communication device integrating therein an antenna with a simple configuration and a stable ground.SOLUTION: A radio communication device 100 comprises: a circuit board 11 on the surface of which a pattern is formed; a radio communication body 31 arranged on one surface of the circuit board 11; a shield cover 21 for covering the radio communication body 31; and an antenna 51 connected with the radio communication body 31. The shield cover 21 and the antenna 51 are composed of one metal sheet. The shield cover 21 is provided with an attachment part 25 for attaching the radio communication device 100 to a product to which the radio communication device 100 is applied. The antenna 51 is a reversed F shaped antenna including an antenna body part 51A, a power supply part 51B, and a short-circuited part 51C. The short-circuited part 51C provided at one end side of the antenna 51 and a top plate 21A of the shield cover 21 facing the radio communication body 31 are connected at a short-circuited part 21C. The power supply part 51B is connected with a power supply land 11A formed on the surface of the circuit board 11.SELECTED DRAWING: Figure 2 |
