A substrate is provided with a transparent electrode in which the pattern is hardly visible even when the transparent electrode layer has been patterned, and a method for manufacturing thereof is provided. On at least one of the surfaces of a transparent film, a first, second, and third dielectric material layer, and a patterned transparent electrode layer are included, in this order, each preferably having a film thickness and refractive index within a specific range. The first and third dielectric material layers are silicon oxide layers containing SiOand SiOas main components, respectively. The second dielectric material layer is a metal oxide layer containing a metal oxide. The transparent electrode layer is a conductive metal oxide layer containing an indium-tin composite oxide as a main component. The refractive indexes of the first (n), second (n), and third (n) dielectric material layers satisfy the relationship n3&#x3c;n1&#x3c;n2.

The substrate with a transparent electrode includes a first dielectric material layer mainly composed of SiO, a second dielectric material layer mainly composed of a metal oxide, a third dielectric material layer mainly composed of SiO, and a transparent electrode layer, in this order on a transparent film substrate. The transparent electrode layer is patterned to have an electrode layer-formed part and an electrode layer non-formed part. The transparent electrode layer is a layer mainly composed of an indium-tin composite oxide and having a thickness of 20 nm to 35 nm. The refractive index nof the first dielectric material layer, the refractive index nof the second dielectric material layer, and the refractive index nof the third dielectric material layer satisfy n&#x3c;n&#x3c;n. The first dielectric material layer, the second dielectric material layer and the third dielectric material layer each have specific thicknesses.

The present invention provides a novel acrylic block copolymer rich in flexibility and excellent in mechanical strength, moldability, oil resistance, heat resistance, thermal decomposition resistance, weather resistance, and compression set, and further rich in reactivity. The present invention also provides compositions, seal products, and automobile, electric, and electronic parts, all of which include the acrylic block copolymer. The acrylic block copolymer includes a methacrylic polymer block (a) and an acrylic polymer block (b), at least one of the polymer blocks containing, in its main chain, at least one acid anhydride group (c) represented by formula (1): (wherein Rs each represent hydrogen or a methyl group and may be the same or different, n represents an integer of 0 to 3, and m represents an integer of 0 or 1).
