A conductive tape comprising a conductive particle-containing layer containing at least a binder resin layer and a plurality of conductive particles, In this conductive tape, the plurality of conductive particles are distributedly disposed independently from each other on one surface of the binder resin layer, a surface of the binder resin layer in a vicinity of each of the conductive particles has an inclination or an undulation with respect to a tangent plane of the binder resin layer in a center portion between adjacent conductive particles, in the inclination, the surface of the binder resin layer around the conductive particle is lacked with respect to the tangent plane, and in the undulation, a resin amount of the binder resin layer right above the conductive particle is smaller than that when the surface of the binder resin layer right above the conductive particle is flush with the tangent plane.

Spacer-containing tape

A spacer-containing tape for enabling the formation of a fine and uniform gap between various members and substrates for general purposes at low cost without the necessity of performing a spacer forming step specialized for each substrate or member on which spacers are to be disposed includes a spacer-dispersed layer containing at least a binder resin layer and a plurality of spacers. In this spacer-containing tape, the plurality of spacers are distributedly disposed independently from each other on one surface of the binder resin layer. It is preferable that the spacers be distributedly disposed regularly on the one surface of the binder resin layer. The area occupancy ratio of the spacers is preferably 35% or less.
