<P>PROBLEM TO BE SOLVED: To provide an image sensor which makes variations in measured values between portions of a light receiving part less likely to occur. <P>SOLUTION: An image sensor includes: a wiring board 1 having an upper surface including a metal layer 3; and a sensor element 2 having a light receiving part 2a and joined to the metal layer 3 by multiple metal members 6. The multiple metal members 6 include a first metal member 6a provided at a first region 5a overlapping with the light receiving part 2a in a plane view and a second metal member 6b provided at a second region 5b around the first region 5a. The first metal member 6a is provided so as to be wider than the second metal member 6b. Differences of temperatures in the light receiving part 2a is reduced between a center region of the light receiving part 2a and a peripheral region of the center region to reduce variations of the sensitivity in the light receiving part 2a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
