PROBLEM TO BE SOLVED: To provide a circuit module so as to reduce the effect of electromagnetic wave noise wherein electronic components are potting-coated with a resin protection body. SOLUTION: In the circuit module, the electronic components 16 are placed on a circuit wiring board 12, the components 16 are connected to an electrode pad 12a of prescribed wire conductors via bonding wires 17, a cylindrical frame 13 is placed to surround the electronic components 16 and the bonding wires 17, and the resin protection body 14 is filled in the frame 13. A shield conductor connected to a ground level is formed to the frame to shut off external noise, and the electronic components 16 are shielded from extraneous noise. COPYRIGHT: (C)2004,JPO&NCIPI |
