A pressure sensor includes a silicon-on-insulator (SOI) substrate, a glass substrate bonded to the SOI substrate by anode bonding, a silicon island formed on a part of a silicon layer of the SOI substrate and surrounded by a groove extending to an insulating layer of the SOI substrate, a through hole formed in the glass substrate, and an output electrode that is made of a conductive material, is disposed inside the through hole, and is electrically connected to an electrode formed on the glass substrate via the silicon island.
