<p>The present invention relates to a sheet-like test device characterized in that the portions other than the portions that function as liquid-absorptive sections of a liquid-absorptive sheet is subjected to a hydrophobicity treatment so that a plurality of liquid-absorptive portions for causing a reaction with a test liquid are formed separately from one another. With the test device of the invention, multiple items of tests can be performed conveniently and expeditiously. The device can be mass-produced in an industrially advantageous manner through a hydrophobicity treatment employing, for example, printing.</p>
