Electromagnetic flowmeter

An electromagnetic flowmeter comprising:

• a measuring tube through which a fluid to be measured flows;
• a printed circuit board having a through-hole through which the measuring tube extends, the printed circuit board being fixed to the measuring tube in a state where the measuring tube is passed through the through-hole;
• a housing having a connecting port at a location facing an end of the measuring tube, the housing accommodating the measuring tube and the printed circuit board, the housing supporting the printed circuit board;
• a joint made of an electrically conductive material, the joint being fixed to the housing, the joint having a cylindrical portion, the cylindrical portion being inserted in the connecting port of the housing, the cylindrical portion forming a fluid passage in cooperation with the measuring tube;
• and
• a connecting component sandwiched by the printed circuit board and the cylindrical portion of the joint, wherein
• the printed circuit board has an electrically conductive portion facing the cylindrical portion, and
• the connecting component has one end that contacts with the electrically conductive portion and an other end that contacts with the cylindrical portion, the connecting component is configured to elastically deform to reduce a distance between the one end and the other end by a predetermined amount, and the connecting component electrically connects the cylindrical portion to the electrically conductive portion.
