Detection device

A detection device comprising:

• a sensor panel that has a detection area in which a plurality of optical sensors are two-dimensionally arranged;
• a light source configured to emit light;
• a member on which an object to be detected is to be placed so that the object to be detected is interposed between the detection area and the light source;
• and
• a flexible printed circuit provided with wiring configured to transmit signals to be transmitted between the sensor panel and a circuit outside the sensor panel, wherein
• a first terminal that is a conductor coupled to wiring provided on the sensor panel is covered by an insulting layer,
• the first terminal and a second terminal face each other with the insulating layer interposed between the first terminal and the second terminal, and
• the second terminal is a conductor that is provided on the flexible printed circuit correspondingly to the first terminal and is coupled to the wiring of the flexible printed circuit.
