PURPOSE: A board having strip conductor arranged at both sides is provided to be sealed off from permeation of gas or fluid by covering at least one side region of the board and a guide member with a layer containing glass. CONSTITUTION: Strip conductors(3,4) arranged at both sides of a board(2), are connected with each other in a hole region(5) through a guide member(6). A guide member region in the outer of a housing(1) and a board region closing by the guide member region, are coated with a layer containing glass(9), thereby eternally sealing a gap(11) between the hole region(5) and the guide member(6). A dielectric paste layer(10) is arranged between the layer containing glass(9), the guide member(6), and a board region closing by the guide member.
