Patent number: 8435899Abstract: A microcolumnar structured material having a desired material. The columnar structured material includes columnar members obtained by introducing a filler into columnar holes formed in a porous material. The porous material has the columnar holes formed by removing columnar substances from a structured material in which the columnar substances containing a first component are dispersed in a matrix member containing a second component capable of forming a eutectic with the first component. The matrix member may be removed. In the columnar structured material, the filler is a conductive material, and an electrode can be structured by electrically connecting the conductive materials in at least a part of a plurality of holes to a conductor.Type: GrantFiled: September 8, 2009Date of Patent: May 7, 2013Assignee: Canon Kabushiki KaishaInventors: Hirokatsu Miyata, Albrecht Otto, Akira Kuriyama, Miki Ogawa, Hiroshi Okura, Kazuhiko Fukutani, Tohru Den
