Abstract: The conversion element member of the present disclosure includes: a conversion element having an opening capable of functioning as a ventilation port and/or a sound-transmitting port; and a waterproof membrane. The conversion element has an outer surface provided with the opening. The waterproof membrane is joined, at a joining portion thereof, to the outer surface of the element so as to cover the opening, the joining portion having a shape surrounding the opening when viewed in a direction perpendicular to the outer surface. The waterproof membrane has a non-joining portion defined as a portion surrounded by the joining portion when viewed in the direction, the non-joining portion having a region overlapping the outer surface when viewed in the direction. A spacing distance D1 between the membrane and the outer surface in the region is 0.01 mm to X mm, where X represents, in an indentation test on the waterproof membrane.
