摘要： The present invention addresses the problem of providing a bonded body which has a high airtightness and exhibits excellent durability under high-temperature and high-pressure conditions. This problem is solved by a bonded body in which a complex of a zeolite and an inorganic porous support, and a dense member are bonded together by an inorganic glass or an inorganic adhesive. The inorganic glass or the inorganic adhesive has a thermal expansion coefficient of 30×10−7/K to 90×10−7/K, and the inorganic glass has a softening point of 550° C. or lower. The present invention also addresses the problem of providing a method of efficiently producing an alcohol by installing a separation membrane in an alcohol synthesis reactor based on a bonding method that gives good sealing performance and durability under high-temperature and high-pressure conditions and in the presence of methanol vapor. This problem can be solved by an alcohol production method of obtaining an alcohol by allowing a raw material gas, which contains at least hydrogen and carbon monoxide and/or carbon dioxide, to react in the presence of a catalyst in a reactor. In the reactor for carrying out the reaction, an alcohol-selective permeable membrane bonded with a dense member is installed, and an alcohol generated by the reaction permeates and is recovered through the selective permeable membrane.
