Abstract
A resin member with a gas permeable member (8) includes a resin member having at least one gas hole (20h) extending therethrough between a front surface (8a) and a back surface (8b), and a sheet-like gas permeable member (50) covering the gas hole. An outer circumferential portion (50p) of the gas permeable member is embedded in the resin member. The resin member further includes first recesses (22) disposed around the gas hole, depressed from at least one of the front surface and back surfaces, and allowing at least a portion of the gas permeable member to be visible in a front-back direction, and second recesses (24) disposed externally of an outer peripheral edge (50e) of the gas permeable member and depressed from at least one of the front surface and the back surface and through which the gas permeable member is invisible in the front-back direction.
