The present invention pertains to a biological sample measurement device, which is intended to be easier to use. The flow board includes a body substrate formed by injection molding methods, which is resistive to methanol or chemical corrosion and has superior mechanical properties. When such a join is identified, it may be evaluated by segmenting the operand relation according to the columns that are compared for equality in the predicate. The mobile terminal is also usable for communication by the user in the awake state.
