PROBLEM TO BE SOLVED: To provide a power supply which is free of malfunctions due to noise, and is easy to assemble. SOLUTION: A printed board mounted with a power circuit and a high-frequency circuit is housed and secured in a shielding case body 1. The shielding case body 1 has a shielding plate 2 integrally formed thereon. A printed board 3 has slits formed at positions corresponding to the shielding plate 2. The high- frequency circuit is installed on the printed board 3 in one of the regions partitioned by a slit portion 4. The power circuit is formed in the other of the regions partitioned by the slit portion 4. After the printed board 3 is secured on the shielding case body 1, an isolating shielding plate 7 is installed on the shielding plate 2. A groove 1b for receiving one end of the isolating shielding plate 7 is formed on the shielding case body 1, and a columnar support portion 2b with a groove 2b formed thereon for receiving the other end of the isolation shielding plate 7 is integrally formed on the shielding plate 2. |
