PROBLEM TO BE SOLVED: To provide wiring pattern conditions for obtaining a good analog image output signal in a high speed drive (5 MHZ or above) contact-type image sensor. SOLUTION: On a CIS substrate, signal linesϕM,ϕRS andϕTR for transmitting a signal to a CCD chip 2-2 extend from digital signal lines Dn and the CCD chip to the emitter follower input, and an emitter follower output line becomes an analog signal line An. In Fig. 1, an analog signal line A1 and a digital signal line D1 from the CCD are wired in different layers.
