Micromixer　has　been　drawing　upon　various　branches　of　engineering　science　and　allied　areas　within　biology　and　biomedicine.　In　this　article,　an　easy　and　fast　fabrication　method　on　hydrophilic　micromixer　using　optically　clear　adhesive　(OCA)　double-sided　tape　together　with　glass　is　proposed.　Different　experiments　on　types　of　planar　hydrophilic　micormixers　with　baffle　structures　are　designed　for　hydrophillic　microchannel.　Flow　is　driven　by　capillary　action　using　surface　tension　and　flow　tests　are　carried　out　to　show　that　the　double-sided　OCA　tape-glass　micromixer　can　achieve　the　mixing　result　of　71　%　in　gray　level　image　analysis.
