<P>PROBLEM TO BE SOLVED: To provide a light-emission detecting device which stably joins substrates having projecting/recessed portions each other, and prevents unnecessary light-emission from reaching detecting means. <P>SOLUTION: A light-emission detecting device 20 has a channel 3 configured by bonding two substrates 16 and 17, and detects the light-emission from the channel. A detecting side substrate 16 having a bonding surface on which recessed portions becoming a part of a wall surface of the channel and a light-shielding film 1 disposed on an area other than the recessed portions are disposed, and a detection surface 6 which is disposed on the back surface of the bonding surface, and making the light-emission from the channel pass through to be detected; and a wiring side substrate 17 disposing a conductive pattern 4 having the thickness of projecting portions and recessed portions on a surface bonded with the detecting side substrate are bonded with each other. In the area in which the light-shielding film is disposed, an adhesive material 7 is disposed according to the thickness of the projecting portions and the recessed portions of the conductive pattern 4, and the detecting side substrate and the wiring side substrate are tightly joined by the adhesive material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
