PROBLEM TO BE SOLVED: To improve the efficiency of installation space even in an existing facility and to measure flow rate at a low cost. SOLUTION: This flow measuring apparatus includes: a first unit container 2 provided at a flow passage end 1 so that fluid entirely flows therein; a second unit container 3 provided in contact with the first unit container 2 and having an opening communicated with the first unit container 2 at its bottom; a pressure difference generating means 4 for generating a pressure difference within a flow passage extending from the first unit container 2 including the opening to the second unit container 3; and a differential pressure detecting means 6 mounted in a hole part provided in the portions of contact between the first unit container 2 and the second unit container 3 for detecting the pressure difference between the first unit container 2 and the second unit container 3.
