The trapped field profile in a 25{times}25 square-columnar Josephson-junction array with a normalized junction critical current {ital i}{sub max} is calculated. It is found that if {ital i}{sub max} of four junctions linking the grain at position (13,7) is replaced by {ital i}{sub max}{sup *}={ital i}{sub max}/10, Josephson vortices with {Phi}{sub 0}/2 flux can appear. This fact implies a unique character of Josephson vortices compared with Abrikosov vortices in type-II superconductor.
