PURPOSE:To contrive improvement both in quality and in reliability of the titled electronic apparatus by a method wherein the main body of a part or various kinds of electronic parts are housed in a case, which is filled with silicon resin of low grade of siloxane. CONSTITUTION:The main body of a transformer, constituted by incorporating a magnetic core into the coil bobbin 8 wound with a primary coil 6 and a secondary coil 7, is housed in an insulated case 11 over which a shielding case 10 is put. Silicon resin 12 of low-grade siloxane, obtained by fully volatilizing cyclic low molecule weight siloxane, is packed in said case 11 and hardened. As a result, the quality and the reliability of the titled electronic machine can be improved.
