PROBLEM TO BE SOLVED: To provide a compact and inexpensive converter of an electromagnetic flowmeter with explosion-proof specifications by providing a pressure-resistant wall for separating an amplification chamber from a terminal chamber and setting the terminal chamber to be an explosion-proof structure with increased safety. SOLUTION: The converter of an electromagnetic flowmeter to be externally wired from a front display, and front comprises: a partition wall, where one end is connected to the bottom surface of the terminal chamber opposite to a wiring through hole; a step section provided at the other end side of the partition wall and the sidewall of the terminal chamber 22; a base plate arranged while one surface is in contact with the step section; a groove that comprises the peripheral end of the base plate, the partition wall, the sidewall of the terminal chamber 22, and the step section and has a specific width, and a specific depth; a first resin filler filled into the groove; a terminal block mounted to the base plate; the terminal through hole that is provided on the base plate, where a conductive plate in the terminal block penetrates; and a second resin filler filled into the terminal through hole. The converter comprises a pressure-resistant explosion-proof partition wall to the wiring through hole by the partition wall, first resin filler, base plate, terminal in the terminal block, and second resin filler.
