Abstract

PURPOSE:To surely prevent permeation of water into a sealed part by filling silicon gel up to the height far covering the connected part between a case and a cover, in the case of fixing by pouring silicon gel on a printed electronic circuit board stored in a sealed case. CONSTITUTION:For example, in the case of storing a photoelectric rotation angle detector in a sealed case 10, after fixing its integrate circuit 12 by binding to the bottom surface of the bottom plate 11 of the case, a cover 16 is put on and a bending agent 17 is filled in the fitting part between the cover 16 and the case 10. Thereafter, silicon gel 15 is injected from an opening part 18 to be filled therein. In this case, silicon gel 15 is poured until its upper surface at least reaches the height for covering the connected part between the case 10 and the cover 16 and a rubber cap 19 is pressed into the cover so that inner space of the case 10 can be sealed airtightly. By this composition, even if any crack or pealing off is generated on the binding agent 17 by heat stress abd so forth generated on the connected part between the cover 16 and the case 10, permeation of water into the sealed part can be prevented perfectly.
