<P>PROBLEM TO BE SOLVED: To provide an elastic wave device which does not have a short circuit between terminal portions even when reflowing is carried out while a load is placed on the elastic wave device in order that the standoff height between the elastic wave device and an electronic circuit board is precisely controlled. <P>SOLUTION: The present invention relates to the elastic wave device which has a surface acoustic wave element (12) provided on a piezoelectric substrate (10) and a terminal portion (20) for electrically connecting the surface acoustic wave element (12) to the outside, where a flank of a projection electrode (22) constituting the terminal portion (20) is covered with a coating portion (37), which has a non-coating part (39). <P>COPYRIGHT: (C)2008,JPO&INPIT |
