Provided is a microchip having a protrusion to which a device for introducing or discharging a liquid sample, a device for causing the liquid sample to flow, or another device is connected, the protrusion retaining strength. The microchip includes a resin substrate (2) which has a fine flow channel (3), a penetrated hole (6) communicating with the fine flow channel (3), and a protrusion (5) formed so as to surround the penetrated hole (6) and project in the thickness direction. The protrusion (5) has a wall thickness (W) and a height (T) satisfying the relationship: (T/10)‰¤W‰¤(T/2). |
