Abstract
An electronic circuit equipment including a substantially box-shaped case body 30 for defining a sealed interior space therein and an electronic circuit board 11 having a plurality of electronic components 12 mounted thereon. The case body comprises a pair of cup-shaped sections 30a clamped together at their opposite ends, and sandwiching between them the circuit board, surrounded and sealingly enclosed by a gas-impermeable flexible sheet 32. A vent hole 20 is provided in one of the sections 30a such that the sheet 32 flexes to absorb pressure fluctuations, and prevents the circuit board from bending.
