PROBLEM TO BE SOLVED: To prevent the erroneous operation due to noise on an electronic component which is accommodated within a package. SOLUTION: This package for electronic component accommodation includes a base 2 having a mount A for carrying thereon an electronic component 4 and having a signal, ground and power lines 5a, 5b and 5c electrically connected to the signal, ground and power electrodes of the electronic component 4 thereon or therein, and also includes a lid member 3 having a recess B for accommodating the component 4 mounted on the mount A therein. By mounting the lid 3 on the base 2 with sealing material 8 provided therebetween, the component 4 is airtightly accommodated within the package. The ground line 5b has at least one branched auxiliary ground line 5d, the signal line 5a is surrounded by the ground and auxiliary ground lines 5b and 5d, at least a part of the auxiliary ground line 5d contains magnetic particles, a metal layer 9 having a plurality of triangular prism-like projections 10 of radio-wave absorbing material arranged thereon is applied on the internal wall of the recess B of the lid 3, and the metal layer 9 is connected electrically to the ground or auxiliary ground line 5b or 5d of the base 2. |
