A sound pickup device comprising: a housing having a porous exterior surface provided with a plurality of holes; a main microphone (111R,111L) that receives sound pressure from an outside of the housing via the plurality of holes to generate a first audio signal, the main microphone being disposed on an inside of the housing; a reference microphone that generates a second audio signal and is disposed near the main microphone on the inside of the housing; a first support member (116,131,132,133) that supports the main microphone and is disposed on the inside of the housing; a second support member (116,113,134) that supports the reference microphone and is disposed on the inside of the housing; a first blocking member (408,131,132,116) that blocks a sound pressure, between the inside of the housing and an inside of the main microphone; a second blocking member (134,113,116,408) that blocks a sound pressure between the outside of the housing and an inside of the reference microphone; and a third blocking member (116,113) that blocks a sound pressure between the inside of the housing and the inside of the reference microphone; a first filling member; wherein; the first filling member fills a space between a surface of the main microphone and a rear face of the housing on an opposite side to the exterior surface and allows the sound pressure from the outside of the housing to pass through, wherein the first filling member serves also as a part of the first support member; and a second filling member (131,132) is disposed on an outer circumference of the main microphone, wherein the second filling member serves also as at least a part of the first blocking member, and the second filling member serves also as a part of the first support member. a housing having a porous exterior surface provided with a plurality of holes; a main microphone (111R,111L) that receives sound pressure from an outside of the housing via the plurality of holes to generate a first audio signal, the main microphone being disposed on an inside of the housing; a reference microphone that generates a second audio signal and is disposed near the main microphone on the inside of the housing; a first support member (116,131,132,133) that supports the main microphone and is disposed on the inside of the housing; a second support member (116,113,134) that supports the reference microphone and is disposed on the inside of the housing; a first blocking member (408,131,132,116) that blocks a sound pressure, between the inside of the housing and an inside of the main microphone; a second blocking member (134,113,116,408) that blocks a sound pressure between the outside of the housing and an inside of the reference microphone; and a third blocking member (116,113) that blocks a sound pressure between the inside of the housing and the inside of the reference microphone; a first filling member; wherein; the first filling member fills a space between a surface of the main microphone and a rear face of the housing on an opposite side to the exterior surface and allows the sound pressure from the outside of the housing to pass through, wherein the first filling member serves also as a part of the first support member; and a second filling member (131,132) is disposed on an outer circumference of the main microphone, wherein the second filling member serves also as at least a part of the first blocking member, and the second filling member serves also as a part of the first support member.
