PROBLEM TO BE SOLVED: To provide a holder for a flow-through type pH electrode having a simple structure, presentable inexpensively in large quantities, capable of measuring continuously even if flow speed of liquid to be measured flowing in a channel is changed, while an adjusting valve is not required to be arranged in a bypass route. SOLUTION: In this holder for the flow-through type pH electrode arranged in series in the bypass route 7 branched from the channel 6 for conveying the liquid 3 to be measured, a measuring part 4 having a prescribed volume and having an inflow port 52 and an outflow port 53 to be connected respectively to the bypass route and an entry of a measuring part of the flow-through type pH electrode 1 is formed, and flow speed in the measuring part 4 can be set in a pressure range suitable for measurement by the flow-through type pH electrode 1 by adjusting a flow rate of the liquid 3 to be measured flowing out from the inflow port 52 in a fixed range by reducing a sectional area of the outflow port 53.
